实验过程
Dilute a 0.370 M solution (in dimethylformamide) of (R)-3-(3-oxiranylmethoxy-phenyl)-isoxazolo[5,4-b]pyridine (140 mg, 0.522 mmol) with ethanol (3.0 mL) and add solution of 4-(3-chlorophenoxy)-piperidine (121.5 mg, 0.574 mmol, 1.1 equivalents) (Table No.1, SM 7) dissolved in ethanol (0.200 M solution). Under a vented argon atmosphere, reflux the reaction mixture overnight. Concentrate the reaction mixture and purify with a Waters Sep-Pak 5 g silica gel cartridge and elute with a graded solvent mixture from 1% methanol in dichloromethane to 5% methanol in dichloromethane to give the title compound (124.6 mg, 50% Yield). Purity by LC/MS=100%, [M+H]+=480
