Participants

Reaction Steps

Hydrochloride gas was bubbled into a solution of product (4-A) (5 g, 15 mmol) in THF (100 mL) at rt for 6 h. The solvent was evaporated to give product (5-A) (3.5 g, 87%) as a brown solid. 1H NMR (300 MHz, CD3OD): δ 7.54-7.51 (d, 1H), 7.41-7.38 (d, 1H), 7.22-7.17 (t, 1H), 7.13-7.08 (t, 1H), 4.55-4.54 (d, 2H), 4.35-4.30 (dd, 1H), 3.50-3.43 (dd, 1H), 3.18-3.08 (t, 1H), 2.91 (s, 3H). LC-MS (M+H)+=230.
