Reaction Steps

Acetyl chloride (0.168 g, 1.5 mmole) was added dropwise with stirring to a cooled solution of 1-(2,4-dimethylphenyl)-5-(2-hydroxyethyl)-3-methyl-tetrahydro-s-triazin-2[1H]-thione (0.60 g, 1 mmole) in dry toluene (30 ml). After 10 minutes the solution was allowed to warm to room temperature and stirring was continued for a further 3 hours. The solution was filtered and the solvent removed under vacuum. The product was chromatographed on a column of silica eluting with dichloromethane containing 2% methanol to yield an oil. Trituration with diethyl ether gave 5-(2-acetoxyethyl)-1-(2,4-dimethylphenyl)-3-methyl-tetrahydro-s-triazin-2[1H]-thione (0.24 g, 35%), m.p. 80°-83° C.
