実験手順

To a stirred mixture of 20.2 parts of 4,5-pyrimidinediamine, 40 parts of pyridine and 144 parts of N,N-dimethylformamide was added dropwise a solution of 24.2 parts of 4-fluorobenzoyl chloride in 36 parts of N,N-dimethylformamide at 10° C. Upon completion, stirring was continued for 30 minutes at room temperature. 600 Parts of water were added. The product was filtered off and dried, yielding 30 parts (70%) of N-(4-amino-5-pyrimidinyl)-4-fluorobenzamide (interm. 11).
