Reaction Steps

To a stirred mixture of 4-amino-1-benzylpiperidine (1.53 mL, 7.5 mmol), K2CO3 (2.28 g, 16.5 mmol) and DMF (15 mL) heated at 50° C. was added dropwise over 60 min bis(2-bromoethyl) ether (0.96 mL, 7.65 mmol). After stirring for 6 hours at 80° C., the solvent was removed by blowing with a stream of nitrogen over 2 hours. The residue was purified on a silica gel column to give 1.7 g (87%) of 4-(1-benzyl-piperidin-4-yl)morpholine as a waxy solid.
