Procedure

In 10 ml of ethanol was dissolved 0.86 g of 35% formalin. To the solution was dropwise added under chilling with ice a solution of 2.35 g of methyl 1-piperazinecarbodithioate in 5 ml of ethanol. The mixture was then stirred for 30 min. at room temperature. The mixture was refluxed overnight under heating after addition of a solution of 1.24 g of 2-methoxyphenol in 5 ml of ethanol under chilling with ice. The reaction mixture was cooled to room temperature. Precipitated crystals were collected by filtration and washed with 5 ml of ethanol to give 1.44 g of the desired compound as a white powder, m.p. 151°-152° C. (decomp.), yield 45.9%.
