The 4-acetyl-6-chloro-3-ethoxy-2-pyrrolidin-1-ylbenzonitrile (0.045 g, 0.15 mmol) was dissolved in methanol (3 mL) and cooled in an ice bath. The sodium tetrahydroborate (0.0058 g, 0.15 mmol) was added and the reaction was monitored by LC/MS. After stirring for 1 h, the reaction was taken up in ethyl acetate and washed with water, sodium bicarbonate, brine and dried over magnesium sulfate to give crude 6-chloro-3-ethoxy-4-(1-hydroxyethyl)-2-pyrrolidin-1-ylbenzonitrile as a clear oil (0.045 g, 100%). LCMS calculated for C15H20ClN2O2(M+H)+: m/z=295.1; found 295.1.
