Vorschrift
To the epoxide from example 40 (900 mg, 4.2 mmol) in DMSO (5 ml) was added propylamine (4 ml, 4.8 mmol) and the reaction mixture was heated to 40° C. for 4 days. The reaction mixture was then cooled and 3M HCl (aq) (10 ml) and water (10 ml) were added before washing with diethyl ether (2×10 ml). This organic layer was discarded. The aqueous layer was basified with NH4OH (5 ml) and extracted with ethyl acetate (3×10 ml). The organic extracts were combined and dried over anhydrous magnesium sulphate, filtered and concentrated in vacuo to give the title compound as an oil (1.15 g, 4.2 mmol, 100%). 1H NMR (CDCl3, 400 MHz) δ: 0.93 (t, 3H), 1.62 (m, 2H), 2.11 (s, 6H), 2.69-2.82 (m, 3H), 3.06 (dd, 1H), 3.60 (bs, 2H), 4.92 (dd, 1H), 5.84 (s, 2H), 7.20 (d, 1H), 7.88 (d, 1H), 8.61 (s, 1H).
