A mixture of methyl 3-(1E)(4-(2-(4-fluorophenyl)-3-hydroxyprop-1-en-1-yl)phenyl)acrylate (0.44 g, 1.4 mmol) and cyclopropylamine (0.14 g, 2.4 mmol) was stirred with MeOH (40 mL) for 3 hours. To the reaction mixture, sodium borohydride (0.09 g, 2.3 mmol) was added and stirred for 30 minutes. Subsequently the reaction mixture was diluted with ethyl acetate (300 mL) and washed successively with water (2×100 ml) and brine (1×100 mL). The organic layer was dried over anhydrous Na2SO4 and concentrated to afford the pure title compound as a pale yellow sticky compound (0.4 g, 80% yield).
