Reaction Steps
Add 2-methyl piperidine (0.871 g, 8.77 mmol) to a solution of methanesulfonic acid 2-[2-(4-bromo-phenyl)-5-methyl-oxazol-4-yl]-ethyl ester (0.316 g, 0.877 mmol) in tetrahydrofuran (5 mL) in a sealed tube, and heat at 60° C. overnight. Cool to room temperature and add dichloromethane. Wash the crude organic material with saturated sodium chloride solution. Dry the organic layer over Na2SO4, filter, and concentrate. Purify on silica gel eluting with 10% ammoniated methanol in dichloromethane to give (+/−)-1-{2-[2-(4-bromo-phenyl)-5-methyl-oxazol-4-yl]-ethyl}-piperidine (0.215 g, 67%): MS (m/e): 363 (M+1).
