Procedure
To a solution of 4-hydroxy-2-(3-methoxyphenylamino)pyrimidine-5-carbonitrile in POCl3 was added DMF 0.5 ml. The solution was refluxed for 3 h. The reaction mixture was cooled to room temperature and poured into ice-water. The solution was adjusted to pH=8-9 by aqueous sodium carbonate solution and extracted with dichloromethane. The combined organic layers were washed with brine, dried over anhydrous Na2SO4, concentrated in vacuo to afford 4-chloro-2-(3-methoxyphenylamino)pyrimidine-5-carbonitrile.
