Reaction Steps

To a solution of 4-cyclopentyl-3-(trifluoromethyl)benzaldehyde (0.25 g, 1.032 mmol) in ethanol (2.5 mL) was added sodium borohydride (0.047 g, 1.238 mmol) and the mixture was stirred at room temperature for 2 h. The mixture was quenched with water, acidified with 6 N HCl, diluted with more water and extracted with CH2Cl2. The CH2Cl2 layer was washed with water, dried over Na2SO4, filtered and concentrated in vacuo to give the title compound (0.22 g). LCMS m/z=227.5 [M−H2O+H]+. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.54-1.72 (m, 4H), 1.77-1.89 (m, 2H), 1.93-2.05 (m, 2H), 3.19-3.28 (m, 1H), 4.52 (d, J=6 Hz, 2H), 5.28 (t, J=5.6 Hz, 1H), 7.52-7.6 (m, 3H).
