Reaction Steps

A mixture of 4-[3-(2-fluoro-4-methanesulfonyl-phenoxymethyl)-[1,2,4]triazol-1-yl]-piperidine hydrochloride salt (Intermediate 6, 0.100 g, 0.256 mmol), potassium carbonate (0.106 g, 0.768 mmol) and 2-chloro-5-ethyl-pyrimidine (0.062 mL, 0.512 mmol) in dimethylformamide (2 mL) was heated at 90° C. for 4 hours or until the starting material was consumed. The reaction was cooled to room temperature, the solution was diluted with water and extracted with ethyl acetate. The organic layer was separated, washed with water and brine, dried over sodium sulfate, filtered and concentration in vacuo. The residue was chromatographed on silica gel (1:1 Hex/EtOAc) to afford the desired product. 1H NMR (CDCl3): δ 8.22 (2H, s), 8.17 (1H, s), 7.68 (2H, m), 7.38 (1H, m), 5.28 (2H, s), 4.92 (2H, d), 4.47 (1H, m), 3.08 (3H, s), 2.94 (2H, m), 2.48 (2H, q), 2.27 (1H, m), 2.18 (1H, m), 1.98 (2H, m), 1.20 (3H, t).
