実験手順
1-(2-Carbomethoxybenzoyl)-2-methyl-4-(3-fluorophenyl)-3-thiosemicarbazide (7.2 g) was dissolved in ethanol (100 ml). The solution was cooled to below 10° and sodium borohydride (1.1 g) added. The mixture was then stirred at room temperature for 60 hours. Water was then added with production of an amorphous precipitate. Dilute hydrochloric acid was then added to the filtrate to bring it to pH 7 and further precipitate removed by filtration. The filtrate was thereupon acidified to yield the title product as a solid, m.p.136°-137°, yield 3.4 g.
