Procedure

A solution of 5-(3,4-dichloro-phenoxy)-pyrimidin-2-ol (0.51 g, 2.00 mmol), N-methyl-N-phenylcarbamoyl chloride (0.34 g, 2.00 mmol) and 1,4-diazabicyclo[2.2.2]octane (0.22 g, 2.00 mmol) in dimethylformamide (15 ml) was stirred at room temperature for 1 hour. Water was added and the precipitates were collected by suction. The solids were dissolved in dichloromethane and the solution was dried over sodium sulphate, filtered and evaporated in vacuo. The residue was crystallised from ethyl acetate:heptane yielding the title compound (0.51 g, 65% yield) as an off-white solid.
