85 °C

To 3-(bromomethyl)-5-fluorobenzonitrile (Intermediate 14, step 1, 10 g, 0.47 mol) in THF (50 mL) was added ammonium hydroxide solution 25% (2.0 L). The resulting mixture was stirred for 2 h at 85° C. It was then cooled down to RT and extracted with dichloromethane. The organic layer was washed with water, brine, dried and concentrated, affording the title compound as a slight yellow liquid (5 g, 71%). 1H NMR (DMSO-d6, 400 MHz): δ 7.6 (d, J=6.6 Hz, 1H), 7.57 (t, J=0.6 Hz, 1H), 7.55 (s, 1H), 3.74 (d, 2H), 1.97 (s, 2H). LC/MS (Method A) 151.0 (M+H)+. HPLC (Method A) Rt: 0.88 min (Purity 98%).
