Reaction Steps

To a mixture of 4-(bromomethyl)-3-chlorobenzonitrile (11 g, 49 mmol, 1.0 equiv) and 6 M NH3 in methanol (200 mL) was stirred at 18° C. for 17 h. Aqueous HCl (1 M, 200 mL) was added, and the water layer was washed with ethyl acetate. The aqueous phase was adjusted to pH 9-10 with 1 M NaOH and extracted with ethyl acetate. The organic layer was washed with water, dried with magnesium sulfate, and concentrated. The residue was purified on silica gel to afford 2.71 g of the title compound. MS (ES+): m/e 167.0 [M+H]+.
