Reaction Steps

A solution of 12.7 g of iodine and 20 g of potassium iodide in 100 ml water was added dropwise to a mixture of 7.25 g of 1,2-dimethylindole and 6.5 g of 1-methyl-1,4,5,6-tetrahydro-2-pyrimidinethiol in 120 ml methanol. The reaction mixture is stirred at room temperature for 2 hours. The crystalline precipitate formed was filtered and recrystallized from a mixture of methanol and ethyl acetate to yield 1,2-dimethyl-3-(1-methyl-1,4,5,6-tetrahydro-2-pyrimidinylthio)-indole hydriodide which melts at 239°-240° (with decomposition).
