Triethylamine (0.42 mmol), HATU (0.15 mmol) and azepane (0.14 mmol) were added and the reaction stirred at room temperature overnight. The resulting solution was purified directly by HPLC, eluting with 10%-98% acetonitrile in water (0.1% formic acid) over 30 minutes. The fractions containing the desired product were concentrated under vacuum to give the title compound (0.022 g). LCMS m/z 292.22 [M+H]+ RT=13.57 min (Analytical Method 1). 1H NMR δ (ppm) (CHCl3-d): 7.2 (s, 1H), 6.95 (s, 1H), 3.7-3.4 (m, 4H), 2.8 (m, 1H), 2.1 (m, 2H), 1.9-1.2 (m, 16H).
