実験手順
A mixture of 3.9 g (0.012 mole) of 4-[4-(2,4-diamino-6-methyl-5-pyrimidinyl)-1-piperazinyl]benzoic acid, 6.5 g (0.039 mole) of diethyl phosphorocyanidate and 6.6 ml (0.047 mole) of triethyl amine in 500 ml of N,N-dimethylformamide (dried over 4H molecular sieves overnight) was stirred at room temperature for five hours. A mixture of 1.8 g (0.014 mole) of glycine methyl ester, hydrochloride, 2 ml (0.014 mole) of triethylamine and 10 ml of N,N-dimethylformamide was added to the suspension and the mixture was stirred at room temperature for another two hours. The solvent was removed under high vacuum (0.1 mm, dry ice-2-propanol trap) at 48° C. The solid residue was dissolved in 200 ml of ice water and neutralized with saturated sodium carbonate solution to pH 8. The solid was collected and washed with 100 ml of water. Recrystallization from acetonitrile gave 2.6 g of the product as a pale yellow solid, mp 255° C. (with decomposition).
