Procedure

Sodium hydride (200 mg, 5.00 mmol, 60% dispersion in mineral oil) was added in several portions into a solution of 4-[6-bromo-2-(trichloromethyl)-1H-1,3-benzodiazol-1-yl]pyrimidin-2-amine (500 mg, 1.23 mmol) and oxan-4-ol (1.00 g, 9.79 mmol) in N,N-dimethylformamide (10 mL) under an atmosphere of nitrogen. The reaction mixture was stirred overnight at room temperature and then filtered through a frit filter. The filtrate was purified on a C18 column (acetonitrile/water, 5:95-80:20) to give 170 mg (28%) of 4-[6-bromo-2-(oxan-4-yloxy)-1H-1,3-benzodiazol-1-yl]pyrimidin-2-amine as a brown solid. LC-MS: m/z=+390 (M+H)+.
