Reaction Steps

Prepared following the same method as for example 6 starting with the morpholin-3-one from example 21 (633 mg, 2.37 mmol). After refluxing in 6M HCl (aq) the reaction mixture was cooled and extracted with diethyl ether (2×20 ml). The organic layers were discarded and the aqueous layer basified by the addition of potassium carbonate. The aqueous residue was then extracted with ethyl acetate (3×20 ml). The organic extracts were combined and dried over anhydrous magnesium sulphate, filtered and concentrated in vacuo to give the title compound as a yellow oil (552 mg, 2.18 mmol, 92%). 1H NMR (CD3OD, 400 MHz) δ: 0.95 (t, 3H), 1.58 (m, 2H), 2.02 (t, 1H), 2.22 (dt, 1H), 2.38 (t, 2H), 2.85 (d, 1H), 2.93 (d, 1H), 3.80 (m, 1H), 3.84 (s, 3H), 4.01 (dd, 1H), 4.50 (dd, 1H), 6.88 (m, 1H), 7.02 (t, 1H), 7.09 (d, 1H). LRMS: m/z 254 (M-H+).
