Participants

Reaction Steps

A mixture of dihydroxypyrimidine methylcarboxylate (B-1) (prepared from 4-methylbenzonitrile by procedures similar to those set forth in Scheme A), 4 eq. of benzoylchloride and 8 eq. of dry pyridine was stirred in dry dichloromethane at room temperature over night. The reaction mixture was diluted with EtOAc and the organic layer was washed twice with 1N HCl, once with brine. The organic layer was dried over anhydrous sodium sulfate, filtered and concentrated in vacuo. The solid residue was triturated with diethyl ether to give product (B-2).
