Dimethyl Sulfoxide → 5-Thiazolecarbonitrile, 4-amino-2-(methylsulfonyl)-

Participants

Reaction Steps

2.7 g (15.8 mmol) of 4-amino-2-(methylsulfanyl)-1,3-thiazole-5-carbonitrile were dissolved in 500 ml of dichloromethane, and 12 g (34.7 mmol) of 50% strength 3-chloroperbenzoic acid were added. The mixture was stirred at RT for 30 min. 6 ml of DMSO were added, and the reaction mixture was washed with saturated sodium bicarbonate solution and water. The organic phase was dried over magnesium sulfate and concentrated on a rotary evaporator. This gave 2.2 g (46% of theory) of the product as a solid.
