Reaction Steps
A mixture of 3-chloro-4-fluorobenzonitrile (5.2 g, 33 mmol), THF (55 mL), and 40% methylamine in water (25 mL, 290 mmol) in a sealed tube was heated to 65° C. for 1.5 hours, cooled to room temperature. The organic phase was washed with brine, dried (Na2SO4), filtered, and concentrated. The resulting solid was dried for about 16 hours under high vacuum in the presence of P2O5 to provide 6.3 g (95%) of the desired product. MS (DCI/NH3) m/z 184, 186 (M+H+NH3)+; 1H NMR (DMSO-d6) δ 7.72 (d, 1H), 7.55 (dd, 1H), 6.70 (d, 1H), 6.52 (br q, 1H), 2.80 (d, 3H).
