Reaction Steps

To a solution of 1-(4-fluorophenyl)-1,3,8-triazaspiro[4.5]decan-4-one (2 g, 8.02 mmol) in dichloromethane (30 mL) and pyridine (1.3 mL, 16.04 mmol, d=0.978), was added benzyl chloroformate (1.17 mL, 8.18 mmol, d=1.195). After stirring at room temperature for 24 hours, the reaction mixture was diluted with dichloromethane (100 mL), washed with dilute citric acid, water and brine. The organic phase was dried over MgSO4, filtered and concentrated to obtain benzyl 1-(4-fluorophenyl)-4-oxo-1,3,8-triazaspiro[4.5]decane-8-carboxylate (2.12 g).
