Oxolane--water (1/1) → Ethyl-[5-(2-isopropyl-4,5-dimethoxy-benzyl)-2-methanesulfonyl-pyrimidin-4-yl]-amine

Participants

Reaction Steps

To a solution of ethyl-[5-(2-isopropyl-4,5-dimethoxy-benzyl)-2-methylsulfanyl-pyrimidin-4-yl]-amine (0.129 g, 0.4 mmol) in 20 mL 1:1 H2O/THF was added OXONE® (0.461 g, 0.8 mmol) in 4.0 mL H2O. After 2 hours, 50 mL H2O was added and the mixture was extracted with ethyl acetate, washed with H2O and washed with brine. The combined organic layers were dried over Na2SO4, filtered and concentrated in vacuo to give ethyl-[5-(2-isopropyl-4,5-dimethoxy-benzyl)-2-methanesulfonyl-pyrimidin-4-yl]-amine (0.131 g, 92%) as a white foam.
