反応手順
2.90 g (14.48 mol) of 2-guanidino-4-thiazole carboxylic acid hydrazide in 50 ml dry ethanol was slurried with 29.1 mmol of ethyl butyrimidate (prepared from 4.41 g (29.1 mmol) of ethylbutyrimidate hydrochloride) for 5 days at 25°. The slurry was filtered and washed with ethanol and ether and dried to give 3.071 g (78%) of 2-guanidino-4-thiazole carboxylic acid 2-butyriminohydrazide.
