Reaction Steps

To a solution of tert-butyl piperidin-4-ylcarbamate (262 mg, 1.31 mmol) (Aldrich) and 2-(N-isopropyl-N-methylamino)benzaldehyde (150 mg, 0.85 mmol) in CH2Cl2 (6 mL) was added Na(OAc)3BH (288 mg, 1.36 mmol) followed by AcOH (0.1 mL). This mixture was stirred for 3 h at RT. The reaction was quenched by adding 2M NaOH—H2O (5 mL) and stirred for 5 min. The mixture was then extracted with CH2Cl2 (2×25 mL), and the organic layer was washed with brine, and dried, and the solvent was removed. The crude material was purified by silica gel column chromatography eluting with 5% NH3-MeOH in CH2Cl2 gave Compound 221.
