実験手順

A mixture of 10.8 parts of 4-(1-piperazinyl)phenol dihydrobromide, 2.6 parts of 2-isothiocyanato-1,1-dimethoxyethane and 54 parts of methanol is stirred and refluxed for 30 minutes. Then there are added 4.7 parts of sodium hydroxide and the whole is stirred overnight at room temperature. The precipitated product is filtered off and crystallized from 4-methyl-2-pentanone, yielding 4.9 parts of N-(2,2-dimethoxyethyl)-4-(4-hydroxyphenyl)-1-piperazinecarbothioamide; mp. 161.4° C.
