Methanol → 2-{4-[4-Cyclopropyl-2-(4-trifluoromethoxy-phenyl)-pyrimidin-5-ylmethylsulfanyl]-2-methyl-phenoxy}-2-methyl-propionic acid ethyl ester

Participants

Reaction Steps

0.399 g (1.2 mmol) of 5-Chloromethyl-4-cyclopropyl-2-(4-trifluoromethoxy-phenyl)-pyrimidine (example 150D]) and 0.300 g (1.0 mmol) of 2-(4-acetylsulfanyl-2-methyl-phenoxy)-2-methyl-propionic acid ethyl ester (example 142C]) were dissolved in 2.0 ml of acetonitrile and 0.08 ml of MeOH and treated with 0.462 g (1.4 mmol) of Cs2CO3. After vigorous stirring for 27 h at ambient temperature and filtration, the solvent was evaporated and the residue redissolved in dichloromethane and filtered again and evaporated. Purification by flash chromatography (SiO2, dichloromethane/n-heptane 1:2 to 4:1 and then AcOEt) afforded 0.428 g of the title compound as colorless oil.
