Procedure

To a mixture of 1-naphthyl acetic acid and 2-(1H-imidazol-1-yl)thiophen-3-amine in anhydrous CH2Cl2 was added 0-(7-azabenzotriazol-1-yl)-N,N,N,N,-tetramethyl uronium hexafluorophosphate and 4-methymorpholine. A small amount of DMF was added to help starting material reagents go into solution. The reaction mixture was stirred overnight under N2 (g) inlet and evaporated under reduced pressure. The resulting residue was purified by flash column chromatography (silica, 10:90 methanol/methylene chloride) to afford N-(2-(1H-imidazol-1-yl)thiophen-3-yl)-2-(naphthalen-1-yl)acetamide (209 mg, 33%). The desired product was purified by preparative HPLC. Method [8] m/z 334.1 (M+H); retention time=4.885. 1H-NMR (CD3OD) δ 8.83. (s, 1H), 7.89-7.80 (m, 2H), 7.77 (d, J=7.8 Hz, 1H), 7.51 (d, J=6.3 Hz, 2H), 7.48-7.32 (m, 5H), 7.17 (d, J=6.3 Hz, 2H), 4.08 (s, 2H).
