Reaction Steps
A mixture of 3-(4-chloro-3-formyl-phenyl)-N-methyl-propionamide (2.30 g, 10.2 mmol) and cyclopropylamine (1.09 mL, 15.3 mmol) in MeOH (109 mL) was stirred for 2 h. Cyclopropylamine (0.364 mL, 5.09 mmol) was added, and the mixture was heated to reflux for 4 h. The mixture was allowed to cool down to rt, and NaBH4 (771 mg, 20.4 mmol) was added by portion. The mixture was stirred for 2 h at rt. The solvents were removed under reduced pressure, and the resulting oil was diluted with EtOAc (500 mL). The resulting mixture was washed with aq. sat. NaHCO3 and brine. The org. layer was dried over MgSO4, filtered, and the solvents were removed under reduced pressure. Purification of the crude by FC (MeOH/CH2Cl2 5:95) yielded the title compound (2.05 g, 75%). LC-MS: tR=0.58 min; ES+: 267.39.
