Procedure

To a stirred mixture of 2-(1-amino-1-methylethyl)-N-(4-fluorobenzyl)-5-hydroxy-1-methyl-6-oxo-1,6-dihydropyrimidine-4-carboxamide (4) and triethyl amine (3 eq) in chloroform, methyl chlorooxoacetate (1.5 eq) was added with an external cooling. Finished the addition, the ice bath was removed and the mixture was stirred at room temperature for 3 H. Reaction mixture was then partitioned between chloroform and 1N HCl. Organic layer was separated, washed with brine, dried (Na2SO4), filtered and concentrated to obtain title product.
