Procedure

A mixture of N-[3-(trifluoromethoxy)benzyl]tetrahydro-2H-pyran-4-amine (190 mg), 2-bromo-1-methyl-1H-imidazole-4-carboxylic acid (100 mg), HATU, diisopropylethylamine (190 mg) and acetonitrile (3 mL) was stirred overnight at room temperature. Acetonitrile was distilled off under reduced pressure and the residue was purified by column chromatography (NH silica gel cartridge; hexane/ethyl acetate=3:1 to 1:2) to give the titled compound (130 mg).
