참여 물질

반응 단계

To a mixture of 6-methyl-5-(1-piperazinylmethyl)-4-(3-nitrophenyl)-2-phenylpyrimidine dihydrochloride (1 g), dichloromethane (10 ml) and triethylamine (0.48 g), was added 2-furoyl chloride (0.31 g) at 5° C. under ice cooling. After stirring for 1 hour at the same temperature, the reaction mixture was concentrated under reduced pressure. The residue was suspended in water and adjusted to pH=9 with aqueous saturated sodium hydrogen carbonate. The precipitate was collected by filtration, washed with water and dried in vacuo to give 6-methyl-5-[4-(2-furoyl)piperazin-1-ylmethyl]-4-(3-nitrophenyl)-2-phenylpyrimidine (1.02 g).
