実験手順
In 100 ml of ethanol was suspended 9.59 g of 7-chloro-2-(2-cyclohexylethyl)-6-nitro-5H-[1,3,4]thiadiazolo[3,2-a]pyrimidin-5-one, and 7 ml of concentrated aqueous ammonia was added thereto at room temperature while stirring. The stirring was continued for 5.5 hours. The precipitate formed was collected by filtration and washed successively with ethanol and diethyl ether to obtain 7.05 g of 7-amino-2-(2-cyclohexylethyl)-6-nitro-5H-[1,3,4]thiadiazolo[3,2-a]pyrimidin-5-one as a pale yellow crystal.
