4-Furan-2-yl-6-methylsulfanyl-5-vinyl-pyrimidin-2-ylamine → 5-Ethyl-4-furan-2-yl-6-methylsulfanyl-pyrimidin-2-ylamine

Participants

Reaction Steps

A solution of 200 mg (0.86 mmol) 4-furan-2-yl-6-methylsulfanyl-5-vinyl-pyrimidin-2-ylamine in 30 ml ethanol was stirred with a spatula end of 10% palladium on charcoal under 1 atm of hydrogen for 16 h at room temperature. After filtration to remove the catalyst, the reaction mixture was concentrated in vacuo and the residue triturated in ether/hexane to afford 60 mg (30%) 5-ethyl-4-furan-2-yl-6-methylsulfanyl-pyrimidin-2-ylamine as an off-white crystalline solid. ES-MS rn/e (%): 236 (M+H+, 100).
