Procedure
A mixture of 3-[4-(4-Tetrazol-1-yl-phenoxymethyl)-thiazol-2-yl]-piperidine hydrochloride (150 mg, 0.407 mmol), 2-chloropyrimidine (0.074 mL, 2.0 eq.) and NaHCO3 (171 mg, 2.03 mmol) in DMF (5 mL) was heated at 90° C. for 4 hours. Water was added and the solution was extracted with ethyl acetate, separated, dried over sodium sulfate, filtered and concentrated. The residue was purified on silica gel (50:50 EtOAc/hexanes) to afford the desired product. 1H NMR (CDCl3): δ 8.91 (1H, s), 8.19 (2H, s), 7.63 (2H, m), 7.26 (1H, s), 7.17 (2H, m), 5.25 (2H, s), 4.97 (1H, m), 4.62 (1H, m), 3.25 (2H, m), 3.07 (1H, m), 2.46 (2H, q), 2.28 (1H, m), 1.88 (2H, m), 1.68 (1H, m), 1.20 (3H, t).
