Procedure

A mixture of 1-[4-(2-Pyrrolidin-3-yl-thiazol-4-ylmethoxy)-phenyl]-1H-tetrazole hydrochloride (From Step 1) (350 mg, 0.959 mmol), 2-chloropyrimidine (0.23 mL, 2.0 eq.) and K2CO3 (398 mg, 2.88 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), 8.21 (2H, s), 7.62 (2H, d), 7.27 (1H, s), 7.17 (2H, d), 5.24 (2H, s), 4.12 (1H, m), 3.98 (1H, m), 3.87 (2H, m), 3.69 (1H, m), 2.56 (1H, m), 2.47 (2H, m), 2.37 (1H, m), 1.21 (3H, t).
