Procedure
To a suspension of 4.5 g. (0.02 mole) of 2-(4-hydroxy-6-propyl-2-pyrimidinylthio)acetamide in 50 ml of phosphorus oxychloride was added 2.98 g. of N,N-diethylaniline. The mixture was heated for ten minutes to reflux temperature. The phosphorus oxychloride was removed in a rotary evaporator and the residue was poured into 150 ml of ice-water. The water mixture was extracted with 100 ml of ether. The ether layer was dried over magnesium sulfate, filtered and evaporated in a rotary evaporator to give an oil. A small amount of the oil was dried in vacuo without purification to afford the analytical sample.
