Potassium Carbonate → HCID 21517690, compound

Participants

Reaction Steps

3.0 gm of 2-methylmercapto-4-chloro-5-nitro-6-cyclohexylamino-pyrimidine were dissolved in 30 ml of acetone, a solution of 1.38 gm of potassium carbonate in 1.5 ml of water was added, and the mixture was admixed with a solution of 1.2 gm of thiomorpholine in 10 ml of acetone. The resulting mixture was stirred at room temperature, whereby after a short time a voluminous, crystalline precipitate was formed which was further increased by addition of water. The mixture was suction-filtered and the filter cake, 2-methylmercapto-4-thiomorpholino-5-nitro-6-cyclohexylamino-pyrimidine, was recrystallized from isopropanol. Yield: 2.3 gm (62% of theory), m.p. 145°-146°C.
