Reaction Steps

To a 0° C. solution of the 4-chlorobenzoyl chloride (4.50 g) in dichloromethane (10 mL) was added an 8M solution of methylamine in ethanol dropwise. The solution was stirred for 16 h and then evaporated to dryness. The residue was diluted with saturated sodium bicarbonate solution (10 mL) and extracted three times with ethyl acetate (3×20 mL), the organics washed with brine (10 mL), dried (MgSO4) and concentrated in vacuo to afford the sub-title compound as a white solid (4.33 g; 97%). 1H NMR (400 MHz, CDCl3) δ 3.00 (3H, s), 7.40 (1H, br) 7.40 (1H, d), 7.70 (1H, d) ppm.
