Reaction Steps

A solution of 162 (1.39 g, 4.77 mmol) and LiOH.H2O (300 mg, 7.16 mmol) in 1:1 THF:water (8 ml) was stirred at room temperature for 24 h. 1 M HCl was added to reach pH=5 and the solvent was evaporated. The title compound was purified by preparative HPLC (Aquasil C18, reverse phase, eluent: MeOH/water) to give 979 mg (78%) of the title compound 163 as a white powder. 1H NMR: (400 MHz, DMSO) δ (ppm): 8.81 (s, 1H), 7.78 (dt, J=8.6, 1.8 Hz, 2H), 7.53 (dt, J=8.8, 2.0 Hz, 2H), 3.44 (t, J=4.9 Hz, 4H), 2.31 (t, J=5.0 Hz, 4H), 2.19 (s, 3H).
