Procedure

2,4-Dichloropyrimidine-5-carboxylic ethyl ester and m-toluidine were allowed to undergo the reaction in acetonitrile in the presence of diisopropylamine to obtain 2-chloro-4-[(3-methylphenyl)amino]pyrimidine-5-carboxylic ethyl ester. Said ester compound was hydrolyzed in THF with 1 M sodium hydroxide aqueous solution, and the resulting carboxylic acid compound was allowed to react with oxalyl chloride in dichloromethane in the presence of a catalytic amount of DMF and then treated with a mixture of aqueous ammonia and ice to obtain 2-chloro-4-[(3-methylphenyl)amino]pyrimidine-5-carboxamide. F: 263.
