Methanethiol → HCID 53970651, compound

Participants

Reaction Steps

31.8 g (0.15 mol) of 2-ethylamino-4-cyclopropylamino-6-chloropyrimidine and 30.6 g of 30 percent strength methanolic sodium methylate solution (0.17 mol) in 25 g of methanol are first introduced into a bomb tube. 8.6 g of gaseous methylmercaptan (0.18 mol) are passed in, whilst cooling. The bomb tube is sealed and is heated to 100° for 24 hours. When the contents of the tube have cooled they are concentrated on a rotary evaporator to give an oil, the latter is taken up in methylene chloride and the solution is extracted with water. After drying over sodium sulphate, filtering and evaporating, the methylene chloride solution gives a yellow oil which crystallises slowly. When recrystallised from methanol-water, 27.3 g of colourless crystals of melting point 75°-6° are obtained.
