الإجراء التجريبي

2-{4-[4-(4-Tetrazol-1-yl-phenoxymethyl)-thiazol-2-yl]-piperidin-1-yl}-pyrimidin-5-ylamine (Example 107) (0.321 mmol) was dissolved in DCM and triethylamine (2 eq.) was added. The reaction was cooled to 0° C., acetylchloride (1 eq.) was added dropwise and the reaction was stirred at room temperature overnight. Water was added and the mixture was extracted with ethyl acetate, dried over sodium sulfate, filtered and concentrated under reduced pressure. Silica gel chromatography of the resulting oil (DCM/MeOH) provided the expected product. 1H NMR (CDCl3): δ 8.84 (1H, s), 8.36 (2H, s), 7.55 (2H, m), 7.19 (1H, s), 7.11 (2H, m), 6.94 (1H, s), 5.16 (2H, s), 4.77 (2H, m), 3.25 (1H, m), 3.01 (2H, m), 2.16 (2H, m), 2.15 (3H, s), 1.75 (2H, m).
