Reaction Steps

To a solution of trans-(4-tert-butoxycarbonylamino-cyclohexyl)-acetic acid ethyl ester (1.04 g, 4 mmol), in toluene (10 ml) at −78° C. a 1.2M solution of DIBAL-H (5.1 ml, 6 mmol) in toluene was added. The mixture was stirred at −78° C. until TLC after 0.5 h indicated completion of the reaction. Water was added and the solution was extracted three times with dichloromethane. The combined organic layers were washed with water and brine, dried over magnesium sulfate, filtered and evaporated. The crude product was used without purification on the next step. MS (m/e): 242.3 (M+H+).
