Procedure

Chloromethyl methyl ether (0.20 ml, 2.63 mmol) was added to a heterogeneous mixture of N-(3-(2H-tetrazol-5-yl)thiophen-2-yl)-2-(4-methoxyphenyl)acetamide (Example 8.1., 580 mg, 1.84 mmol) and potassium carbonate (1.36 g, 9.84 mmol) in DMF (10 ml). After stirring for 72 h, the solution was diluted with water and extracted with methylene chloride. The combined organic extracts were dried over magnesium sulfate, filtered and concentrated under reduced pressure. The residue was directly purified by HPLC to yield N-(3-(2-(methoxymethyl)-2H-tetrazol-5-yl)thiophen-2-yl)-2-(4-methoxyphenyl)-acetamide. Method [7] Retention time 6.60 min by HPLC (MH+ 360). 1H NMR (300 MHz, CDCl3) δ 10.58 (s, 1H), 7.47 (d, J=5.7 Hz, 1H), 7.33 (d, J=8.4 Hz, 2H), 7.00 (d, J=8.4 Hz, 2H), 6.93 (d, J=5.7 Hz, 1H), 5.77 (s, 2H), 3.87 (s, 3H), 3.86 (s, 2H), 3.37 (s, 3H).
