Procedure

A solution of 2-(2-acetylamino-4-diacetylamino-1,6-dihydro-6-oxo-5-pyrimidinyl)acetaldehyde (1.74 g, 5.92 mmol) and dimethyl N-(4-aminobenzoyl)-L-glutamate (J. Am. Chem. Soc., 1958, 80, 5779) (1.74 g, 5.92 mmol) in acetic acid (90 ml) was stirred for 10 minutes. Sodium cyanoborohydride (0.84 g, 13.4 mmol) was added in small portions over 1 hour. After an additional 30 minutes, the reaction was spin evaporated in vacuo to a thick oil. The oil was dissolved in ethyl acetate (500 ml) and washed with 5% aqueous sodium bicarbonate until neutral, water (50 ml), brine (50 ml), dried with magnesium sulfate and spin evaporated in vacuo. Recrystallization from ethyl acetate, with filtration to remove insolubles, yielded 1.5 g (49% of theory) of dimethyl N-[4-[2-(2-acetylamino-4-diacetylamino-1,6-dihydro-6-oxo-5-pyrimidinyl)ethylamino]benzoyl]-L-glutamate, mp 168°-178° C. Recrystallization from ethyl acetate (Norite) gave 0.830 g (25% of theory) of the analytical sample, mp 176°-179° C.
