Procedure

A mixture of 4-[4-(4-methylsulfonyl-phenoxymethyl)-thiazole-2-yl]-piperidine hydrochloride (100 mg, 0.24 mmol), 2-chloropyrimidine (30 mg, 1.1 eq.) and diisopropylethylamine (122 mg, 4 eq.) in i-PrOH (5 mL) was heated at 90° C. for 1.5 hours. The solvent was removed in vacuo. The residue was purified on silica gel (60% EtOAc in hexanes) to afford the desired product. 1H NMR (CDCl3): δ 8.32 (2H, d, J=4.8 Hz), 7.88 (2H, d, J=8.8 Hz), 7.23 (1H, s), 7.12 (2H, d, J=8.8 Hz), 6.49 (1H, t, J=4.8 Hz), 5.24 (2H, s), 4.89 (2H, m), 3.32 (1H, m), 3.06 (2H, m), 3.04 (3H, s), 2.22 (2H, m), 1.81 (2H, m).
