Versuchsvorschrift

According to general procedure A, from #43 (176 mg, 0.184 mmol, 1 eq.), dichloromethane (4 mL, 0.05 M) and diethylamine (4 mL) was synthesized the crude desired material, which was purified by reverse phase chromatography (Method C). The resulting trifluoroacetic acid salt was dissolved in methanol, treated with a 4 M solution of hydrochloric acid in dioxane, and concentrated in vacuo to give #45 (100 mg, 70%) as a white solid. LC-MS: m/z 734.6 [M+H+], retention time=0.72 minutes; 1H NMR (400 MHz, CD3OD), presumed to be a mixture of rotamers, characteristic signals: δ 7.18-7.31 (m, 5H), 5.41-5.47 and 5.55-5.62 (2 m, total 1H), 3.73 and 3.76 (2 s, total 3H), 3.35 and 3.36 (2 s, total 3H), 3.10 and 3.15 (2 br s, total 3H), 1.62 and 1.64 (2 s, total 3H), 1.53 and 1.55 (2 s, total 3H), [1.25 (d, J=6.6 Hz) and 1.29 (d, J=6.5 Hz), total 3H], 0.84-0.91 (m, 3H).
