실험 절차

In 10 ml of ethanol was dissolved 0.86 g (10 mmol.) of 35% formalin. To thesolution placed in an ice bath was further added a solution of 1.94 g (10 mmol., purity 90.7%) of methyl 1-piperazinecarbodithioate in 4 ml of ethanol. The resulting mixture was then stirred for 30 min. at room temperature. To the mixture placed in an ice bath was dropwise added a solution of 2.12 g (10 mmol.) of propyl gallate in 4 ml of ethanol. The mixture was stirred overnight at room temperature and subsequently refluxed under heating for 4 hours. The mixture was cooled to room temperature. Precipitated crystals were collected by filtration and washedwith ethanol to give 1.848 g of the desired compound as a grayish powder, m.p. 142°-144° C. (decomp.), yield 31.3%.
