90% | With boron trichloride; tetra-(n-butyl)ammonium iodide In dichloromethane at -78 - 20℃; | In a 100 mL round bottom flask, 3- methoxy-5-methyl-benzonitrile (500 mg, 3.39 mmol) was dissolved in 15 mL dry DCM, and tetrabutylammonium iodide (1.38 g, 3.73 mmol, 3.5 eq.) was added. The flask was cooled to -78 0C. BCk (1 M in DCM, 11.87 mL, 33.16 mmol) was added to the reaction dropwise. The reaction mixture was stirred at -78 0C and warmed up to room temperature overnight. The reaction mixture was quenched with ice and neutralized with saturated NaHCCh solution. DCM was added to extract the <n="425"/>reaction mixture. The organic layer was concentrated down and purified (silica gel, 0-10percent MeOH/DCM) to give a light yellow solid (408 g, 90percent). LC-MS shows 132.0 (M-I). 1H NMR (300 MHz, CDCb): δ 7.20 (s, 1 H), 6.96 (s, 1 H), 6.91 (s, 1 H), 2.37 (s, 3 H). |
77% | Stage #1: With boron trichloride; tetra-(n-butyl)ammonium iodide In dichloromethane at 20℃; for 0.5 h; Stage #2: With water In dichloromethane at 0℃; for 0.333333 h; |
BC13 (50 ml, 50 mmol, 1 M in DCM) was added dropwise to a solution of 3-methoxy- 5-methylbenzonitrile (Example 2) (2.101 g, 14.27 mmol) and Bu4NI (5.80 g, 15.7 mmol) in dry DCM (50 ml) AT-78 °C. The cold bath was removed and the mixture stirred at ambient temperature for 30 min. Ice was added and the mixture stirred 20 min, and neutralized with sat. NAHCO3. ORGANIC layer separated and product isolated by flash chromatography using 1- 2percent MeOH in DCM. Yield 1.465 g (77percent), white SOLID,-80percent pure by NMR. IN NMR (400 MHz, CDCl3) 8 2.33 (s, 3 H), 6.89 (s, 1 H), 6.92 (s, 1 H), 7.03 (s, 1 H). 13 NMR (100 MHZ, CDCL3) 8 21.12, 112. 79, 115. 85, 118. 70,121. 19,125. 27,141. 20, 155.81. |
