Procedure

Concentrated hydrochloric acid (27.5 mL) was added to a solution of compound 6 (11.0 g, 17.1 mmol) and ethanol (82.5 mL). The mixture was stirred until reaction was complete as monitored by TLC. The mixture was concentrated in vacuo and dichloromethane added and concentrated again, this was repeated until a solid was obtained. The solid was then slurried with t-butylmethyl ether (30 mL), filtered, and the organic layer dried (MgSO4) and concentrated in vacuo to give the title compound 7 (10.0 g, 99%): δH (360 MHz: DMSO, 70° C.) 1.30–1.50 (m, 2H), 1.85 (br s, 4H), 2.12 (br, d, 2H), 2.48 (s, 3H), 2.91 (br t, 1H), 3.81 (s, 3H), 3.87 (br s, 1H), 4.71 (s, 2H), 7.14 (d, 1H), 7.29 (s, 1H), 7.40 (d, 1H), 7.57–7.68 (m, 4H), 7.80–7.90 (m, 3H), 8.09 (d, 1H), 8.82 (br s, 2H).
