実験手順

A mixture of 3.2 g (0.0091 mole) of 4-[4-(2,4-diamino-6-propyl-5-pyrimidinyl]-1-piperazinyl]benzoic acid, 4.9 g (0.030 mole) of diethyl phosphorocyanidate and 4.2 ml (0.030 mole) of triethylamine in 200 ml of of N,N-dimethylformamide (dried over 4 Å molecular sieves overnight) was stirred at room temperature for two hours. To the resulting clear solution was added a mixture of 2.4 g (0.010 mole) of diethyl glutamate hydrochloride and 1.4 ml (0.010 mole) of triethylamine in 10 ml of N,N-dimethylformamide, and the solution was stirred for another hour. The solvent was removed under high vacuum (0.1 mm, dry ice-2-propanol trap) at 40° C. The gummy residue was poured into 100 ml of ice water. The solid was collected and recrystallized from N,N-dimethylformamide to give 1.9 g of the product as an off-white powder; mp 175°-180° C.
