Reaction Conditions

Reaction Steps

To a solution of 4-nitrophenol (8.04 g, 58 mmol) in DMF (36 ml) is added at 0° C. sodium hydride (2.5 g, 63 mmol, 60% in mineral oil) and stirring is continued for 30 minutes at r.t. A solution of 4-chloro-6-methylsulfanyl-pyrimidine (8.44 g, 52.5 mmol) in DMF (12 ml) is added and the reaction mixture is sealed in a reaction tube and heated in the microwave to 130° C. for 20 minutes. The reaction mixture is taken up in ethyl acetate and water. The organic phase is washed dried and evaporated. Recrystallization from ethyl acetate results in 6.08 g (44%) of an off-white powder of sufficient purity.
