실험 절차

A mixture of 0.8 g (2.6 mmol) of 5-methyl-4-methylsulfonyl-2-(4-trifluoromethyl-1H-1-pyrazolyl)pyrimidine, 0.44 g (2.6 mmol) of 3-hydroxy-5-trifluoromethylthiophene and 0.72 g (5.2 mmol) of K2CO3 in 10 ml of DMF is stirred at 60° C. for 6 h and then at RT for 48 h. It is subsequently poured into 20 ml of water and extracted with four times 15 ml of CH2Cl2. The combined organic phase is dried over Na2SO4, filtered and concentrated. Chromatographic purification on silica gel with heptane/ethyl acetate (3:7) as eluent gives 0.5 g of 5-methyl-2-(4-trifluoromethyl-1H-1-pyrazolyl)-4-(5-trifluoromethyl-3-thienyloxy)pyrimidine as colorless crystals.
