To a solution of N-(4-((trans)-2-aminocyclopropyl)phenyl)acetamide, hydrochloride (150 mg, 0.662 mmol) in a mixture of dichloromethane (10 mL) and methanol (5 mL) was added tert-butyl 4-formylpiperidine-1-carboxylate (141 mg, 0.662 mmol) and stirred for 5 min, then Na(OAc)3BH (210 mg, 0.992 mmol) was added and stirred for 30 min. The crude was diluted with DCM (100 mL) and poured into sat NaHCO3 solution (50 mL). The separated organic layer was washed with water (20 mL), brine solution (20 mL) and the organic layer was dried over anhy sodium sulphate and concentrated. The crude was purified using silica gel (100-200 mesh) column chromatography, eluting with MeOH in DCM. Compound eluted in 4% MeOH in DCM to afford tert-butyl 4-((((trans)-2-(4-acetamidophenyl)cyclopropyl)amino)methyl)piperidine-1-carboxylate (150 mg, 0.387 mmol, 58.5% yield). LCMS (ES) m/e 387.96 (M+H), 95.06%
