Reaction Steps

To a solution of piperidin-4-yl-carbamic acid tert-butyl ester 3 (10 g, 50 mmol) in 100 ml of methanol are added sodium carbonate (21.2 g, 200 mmol) and 2-bromoethanol (7.1 ml, 100 mmol). The mixture is stirred over night. The solvents are then evaporated and the residue is triturated with DCM, filtered and evaporated again. The crude product is purified by chromatography using EtOAc/MeOH (saturated with ammonia): 9/1.
