Participants

Reaction Steps

165 g of 2-methoxy-5-methyl-2,4,6-cycloheptatrien-1-one and 84 g of thiourea were added to 255 g of 28% sodium methoxide/methanol solution and everything was stirred for 30 minutes at room temperature. Next, 60 ml of methanol was added, and then acetic acid was added until the pH value of the resulting solution became 5 or so. The crystals thus precipitated were separated by filtration, fully washed with methanol and then dried.
