YieldReaction ConditionsOperation in experiment
89% With dmap; triethylamine; In dichloromethane; for 24h; A solution of R-1 (25.0 g, 113 mmol) in CH2C12 (250 mL) is treated with TEA (31 mL, 225 mmol), TsCl (23.6 g, 124 mmol), and DMAP (2.75 g, 23 mmol). The mixture is stirred for 24 h then filtered and concentrated in vacuo. The residue is dissolved in EtOAc and washed with saturated aqueous ammonium chloride and brine. The organics are collected and volatiles are removed in vacuo. The crude residue is triturated with Et20 and solid filtered and collected to afford 1-1 (36.9 g, 89%) m/z 367.9 [M+].
65% With dmap; triethylamine; In dichloromethane; for 24h; Synthesis of Intermediate I-1 [0107] [0108] A solution of R-1 (5.0 g, 23 mmol) in CH2Cl2 is treated with TEA (6.5 mL, 47 mmol) and DMAP (0.57 g, 4.7 mmol). The mixture is stirred for 24 h then concentrated in vacuo. The residue is dissolved in EtOAc and washed with saturated aqueous ammonium chloride and brine. The organics are collected and volatiles are removed in vacuo. The crude residue is triturated with Et2O and solid filtered and collected to afford I-1 (5.6 g, 65%) m/z 367.9 [M+].
65% With dmap; triethylamine; In dichloromethane; for 24h; [0140] A solution of R-3 (5.0 g, 23 mmol) in CH2Cl2 istreated with TEA (6.5 mL, 47 mmol) and DMAP (0.57 g, 4.7mmol). The mixture is stirred for 24 h then concentrated invacuo. The resiude is dissolved in EtOAc and washed withsaturated aquoues ammonium chloride and brine. The organicsare collected and volatiles are removed in vacuo. The crude resiude is triturated with Et20 and solid filtered andcollected to afford 1-12 (5.6 g, 65%) m/z 367.9 [M+].
With dmap; triethylamine; Step 1: Preparation of tert-butyl 6-(tosyloxy)-2-azaspiro[3.3]heptane-2-carboxylate A magnetically-stirred solution of <strong>[1147557-97-8]tert-butyl 6-hydroxy-2-azaspiro[3.3]heptane-2-carboxylate</strong> (5.0 g, 23 mmol) in dichloromethane (46 mL) was successively treated with triethylamine (6.5 mL, 47 mmol), 4-toluenesulfonyl chloride (4.9 g, 26 mmol), and 4-dimethylaminopyridine (0.58 g, 4.7 mmol). The reaction mixture was stirred at room temperature overnight and was then filtered through a fritted pad of Celite diatomaceous earth. After concentration of the filtrate under reduced pressure, the residue was taken up in ethyl acetate and was successively washed with saturated aqueous solutions of ammonium chloride and sodium chloride. The organic phase was dried over anhydrous magnesium sulfate, filtered, and concentrated under reduced pressure. The residue was triturated with diethyl ether and collected by filtration to provide the titled intermediate. LCMS-ESI+ (m/z): [M-isobutylene+H]+ calcd 312.08; found 311.81.
