With sodium hydride; In N,N-dimethyl-formamide; at 135℃; for 1.5h; | To a solution of 4-[(2,4-dichloro-5-methoxyphenyl)amino]-7-fluoro-6-methoxy-3-quinolinecarbonitrile (250 mg, 0.64 mmol) and 1-methylpiperidine-3-methanol (165 mg, 1.28 mmol) in 6 mL of N, N'-dimethylformamide at 135° C. is added sodium hydride (92 mg, 3.8 mmol) in portions. After 1 hour an additional 92 mg of sodium hydride is added to the reaction mixture at 135° C. After 30 minutes the reaction mixture is poured into saturated sodium bicarbonate. After stirring for 15 minutes the solid is collected by filtration. The residue is purified by flash column chromatography, eluting with a gradient of 5percent methanol in dichloromethane to 1percent ammonium hydroxide in 10percent methanol in dichloromethane. After an additional purification by flash column chromatography eluting with a gradient of 5percent methanol in dichloromethane to 25percent methanol in dichloromethane, 4-[(2,4-dichloro-5-methoxyphenyl)amino]-6-methoxy-7-[(2-(1-methyl-3-piperidinyl)methoxy]-3-quinolinecarbonitrile is obtained, mp 176-178° C.

99% | With dmap; triethylamine; In dichloromethane; at 20℃; for 2h; | Toluene-4-sulfonic acid 1-methyl-piperidin-3-ylmethyl ester A mixture of 2.07 g (16 mmol) 1-methyl-3-piperidinemethanol, 3.35 g (18 mmol) p-toluensulfonyl chloride, 0.58 g (5 mmol) 4-dimethylaminopyridine and 2.23 mL (16 mmol) NEt3 in 30 mL DCM was stirred for 2 h at room temperature. The mixture was washed with water and evaporated to dryness to yield 4.5 g (99%) of the title compound as yellow oil which was used without further purification. MS(m/e): 284.1 (MH+). |
58% | With triethylamine; In dichloromethane; at 0 - 20℃; for 6h; | To a stirred solution of 1 -methyl-3 -hydroxymethylpiperidine (2 g, 15.5 mmol) in DCM (30 mL) at 0C, triethylamine (4.9 g, 46 mmol) and tosyl chloride (4.41 g, 23.2 mmol) were added and allowed the mixture to stir at room temperature for 6 h. After completion, the reaction mixture was diluted with water (30 mL) and extracted with DCM (3 x 30 mL). The combined organic layer was dried over sodium sulfate and concentrated. The resulting crude was purified by flash chromatography (silica gel, 12 g cartridge) using 0-20% EtOAc in hexanes as eluent to obtain (l-methylpiperidin-3-yl)methyl 4- methylbenzenesulfonate (Yield: 2.50 g, 58%) as white solid. LCMS (ES) m/z = 284.36 [M+H]+; NMR (400 MHz, DMSO-d6) d ppm: 0.87-0.95 (m, 1H), 1.33-1.50 (m, 4H), 1.63 (m, 1H), 1.80-1.85 (m, 2H), 2.06 (s, 3H), 2.42 (s, 3H), 2.46-2.52 (m, 1H), 3.90 (m, 2H), 7.48 (d, J= 8.0 Hz, 2H). 7.78 (d, J= 8.0 Hz, 2H). |
With dmap; In dichloromethane; at 20℃; for 12h;Cooling with ice; | 10.0 g of 1-methyl-3-piperidinemethanol are dissolved in 100 ml of dichloromethane, and 9.46 g of 4-dimethylaminopyridine and 15.5 g of p-toluenesulfonyl chloride are added with ice cooling The reaction solution is stirred at room temperature for twelve hours and then washed with saturated NaHCO3 solution and dried over MgSO4, and the solvent is removed under reduced pressure. The resulting residue is dissolved in 150 ml of acetone, and 39.5 g of sodium iodide are added. The reaction mixture is heated at the boil under reflux for two hours. The solvent is then removed under reduced pressure, and the residue is taken up in 300 ml of ethyl acetate and washed twice with in each case 100 ml of water. The organic phase is dried over MgSO4 and then concentrated under reduced pressure. This gives 9.4 g of 3-iodomethyl-1-methylpiperidine. C7H141N (239.10), LCMS (ESI): 240.0 (M+H+). |
With triethylamine; In dichloromethane; at 20℃; for 5h; | Into a 250 mL round bottom flask containing a solution of (l-methylpiperidin-3- yl)methanol (8.0 g, 62 mmol) in dichloromethane (80 mL) was added triethylamine (17 mL, 125 mmol) followed by the addition of p-toluenesulfonyl chloride (14.2 g, 75 mmol) and the reaction mixture stirred at room temperature for 5 h. The reaction mixture was diluted with dichloromethane and washed with water and brine solution. The organic fraction was dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The crude was purified by flash chromatography eluting with methanol in dichloromethane (5-7%) to afford (1-methylpiperidin-3-yl)methyl 4-methylbenzenesulfonate as a liquid. 1H NMR (DMSO-d6; 400 MHz): delta 7.80 (d, J = 7.8 Hz, 2H), 7.11 (d, J = 7.8 Hz, 2H), 4.01-3.91 (m, 2H), 3.21-3.16 (m, 2H), 2.64-2.58 (m, 2H), 2.43 (s, 3H), 2.42-2.29 (m, 1H), 2.09 (s, 3H), 1.77-1.74 (m, 2H), 1.62- 1.59 (m, 2H). MS calc'd [M+H]+ 284.1, found 284.4. |
