2-(4-Methoxyphenyl)-N-(2-(1-trityl-1H-imidazol-4-yl)thiophen-3-yl)acetamide (561 mg, 1.01 mmol) in TFA (10 ml) was stirred for 1 h. The solution was concentrated under reduced pressure and the residue was directly purified by HPLC to yield N-(2-(1H-imidazol-4-yl)thiophen-3-yl)-2-(4-methoxyphenyl)acetamide. Method [8] Retention time 3.37 min by HPLC (MH+ 314). 1H NMR (300 MHz, DMSO) δ 10.28 (s, 1H), 8.60 (s, 1H), 7.59 (s, 1H), 7.53 (d, J=5.7 Hz, 1H), 7.49 (d, J=5.7 Hz, 1H), 7.23 (d, J=8.4 Hz, 2H), 6.90 (d, J=8.4 Hz, 2H), 3.73 (s, 3H).
