Procedure

5-Pyridin-4-yl-thiophene-3-carboxylic acid (0.4 mmol) was dissolved in MeCN (2 mL). 1-[1,4]Diazepan-1-yl-ethanone (1.8 mmol), and HATU (0.4 mmol) were added and the reaction mixture stirred for 72 hours. DCM (20 mL) was added and the organic solution was separated and the solvent removed by evaporation. The residue was purified by HPLC, eluting with 10%-90% acetonitrile in water (0.1% formic acid) over 30 minutes. The fractions containing the desired product were concentrated under vacuum and freeze-dried to give the title compound as a white solid (33 mg). LCMS m/z 287.09 [M+H]+ RT=5.20 min. (Analytical Method 2). 1H NMR (400 MHz, MeCN-d): δ 8.6 (d, 2H), 7.95 (d, 2H), 7.9 (s, 1H), 7.8 (s, 1H), 3.6 (t, 2H), 3.5 (t, 2H), 1.8-1.6 (m, 6H).
