Reaction Steps

0.15 ml of ethyl chloroformate were added, whilst ice-cooling, to a mixture of 0.360 g of N-[2-(1-piperazinyl)ethyl]-α-[4-(2,3,4,5-tetrahydro-3-oxo-1,2,4-triazin-6-yl)phenoxy]acetamide [prepared as described in step (a) above], 0.13 g of sodium bicarbonate, 10 ml of water and 50 ml of tetrahydrofuran, and the mixture was stirred for 30 minutes. The reaction mixture was then concentrated by evaporation under reduced pressure, and the residue was purified by column chromatography through silica gel (eluent: a 1:1 by volume mixture of ethanol and methylene chloride), followed by recrystallization from ethanol, to give 0.264 g of the title compound as colorless fine crystals melting at 200°-240° C. (with decomposition).
