Reaction Steps

Into a 100-milliliter, 4-necked flask equipped with a reflux condenser, thermometer and stirrer, were charged 5.51 g of 6-chloro-2,4-dimethoxy-5-methylthiopyrimidine and 50 ml of tetrahydrofuran. After causing the pyrimidine derivative to dissolve completely in the solvent, a 15% aqueous solution of sodium methyl mercaptan (commercially available; product of Tokyo Kasei Kogyo K.K.) was added dropwise and the resultant mixture was refluxed for 5 hours.
