N-[2-(4-Fluoro-3-methoxyphenyl)-2-hydroxyethyl]propanamide → HCID 57440686, compound

Participants

Reaction Steps

Prepared following the same method as for example 3 starting with the amide from example 18 (585 mg, 2.42 mmol). After refluxing in 6M HCl (aq) the reaction mixture was cooled and extracted with diethyl ether (2×50 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 (3×50 ml). The organic extracts were combined and dried over anhydrous magnesium sulphate, filtered and concentrated in vacuo to give the title compound as a pale yellow oil (448 mg, 1.97 mmol, 81%), 1H NMR (CD3OD, 400 MHz) δ: 0.96 (t, 3H), 1.58 (m, 2H), 2.63 (m, 2H), 2.79 (d, 2H), 3.96 (s, 3H), 4.77 (t, 1H), 6.90 (m, 1H), 7.03 (t, 1H), 7.11 (d, 1H). LRMS: m/z 228 (M-H+).
