To a solution of 2,4-dichloro-pyrimidine-5-carbonyl chloride (197.7 mg, 0.94 mmol) in CH2Cl2 (9.4 mL) at RT is added Me2NH (2.0 M THF solution, 390 μL, 0.78 mmol) and Et3N (108.6 μL, 0.78 mmol) at 0° C. The reaction mixture is stirred overnight at RT. After adding water, the mixture is extracted with CH2Cl2. The organic layer is dried and concentration under reduce pressure give 2,4-dichloro-pyrimidine-5-carboxylic acid dimethylamide (272.5 mg, quant). ESI-MS m/z: 221 [M+1]+, Retention time 1.94 min (condition B).
