Reaction Steps

A mixture of 3-cyclopentyloxy-4-methoxy-benzaldehyde (417 mg, 1.895 mmol), 2-amino-5-bromopyrazine (300 mg, 1.724 mmol), sodium triacetoxyborohydride (1.5 eq) and glacial acetic acid (3 eq) in dichloromethane (10 ml) was stirred at room temperature overnight. Then the reaction mixture was diluted with ethyl acetate, and washed with water. The oraganic layer was dried over MgSO4 and filtered. The filtrate was concentrated to give the crude product, which was purified by ISCO (SiO2 flash column chromatography) (Hexane/ethyl acetate=100/0 to 3/2) to give about 400 mg of 6-bromo-pyrazin-2-yl)-(3-cyclopentyloxy-4-methoxy-benzyl)-amine. Yield: 61%.
