Procedure
To a mixture of 4-methylamino-2-phenylpyrimidine-5-carboxylic acid (7 g) and dimethylformamide (50 ml) is added triethylamine (3.1 g) at room temperature, and the mixture is stirred for 10 minutes, and thereto is added diphenylphosphoryl azide (8.4 g) at the same temperature. The reaction mixture is stirred at 120° C. for four hours, and concentrated under reduced pressure. The residue is poured into ice-water, and the precipitates are collected by filtration, washed with water, washed with ethanol, and recrystallized from chloroform to give the desired compound (5 g).
