4-Acetyl-6-chloro-3-ethoxy-2-(3-methoxyazetidin-1-yl)benzonitrile (30 mg, 0.1 mmol was dissolved in methanol (5 mL) cooled to 0° C. and sodium tetrahydroborate (5.5 mg, 0.14 mmol) was added. Reaction was stirred for 1 h at 0° C. The reaction was partitioned between EtOAc and water. The combined organic layer was washed with water and saturated NaHCO3, brine, dried over Na2SO4, filtered and concentrated to give crude 6-chloro-3-ethoxy-4-(1-hydroxyethyl)-2-(3-methoxyazetidin-1-yl)benzonitrile (0.030 g, 100%). LCMS calculated for C15H20ClN2O3(M+H)+: m/z=311.1; found: 311.1.
