Reaction Steps

A drop of DMF was added to a stirred solution of 6-chloropyrimidine-4-carboxylic acid (5.5 g, 34.7 mmol) and (COCl)2 (12 mL) in DCM (100 mL). The mixture was stirred at 25° C. for 2 h. The solvent was evaporated under reduced pressure to give crude 6-chloropyrimidine-4-carbonyl chloride (6.0 g, yield: 97.7%). 1H NMR (400 MHz, DMSO-d6) δ 9.20 (s, 1H), 8.10 (s, 1H).
