Reaction Steps

A solution of the product from Step F, Example 1 (41.4 mg, 0.10 mmol) in methanol (2.0 mL) was treated with potassium hydroxide (1.0 mL, 40% aq). The reaction was stirred at 40° C. for 48 hours and concentrated in vacuo. The residue was purified by silica gel chromatography (methanol:dichloromethane) to provide pure title compound (3.7 mg). MS (ESI) m/z 335 (MH+); 1H-NMR (CDCl3) δ 8.19 (bs, 1H), 7.48 (d, 2H), 7.27 (m, 2H), 7.07 (t, 1H), 7.00 (t, 1H), 6.86 (d, 2H), 6.61 (s, 1H), 3.96 (t, 2H), 2.5 (m, 6H), 1.4 (m, 8H).
