Reaction Conditions

Reaction Steps

A mixture of potassium phthalimide (1.85 g, 3 mmol) and 3-bromocyclohexene (1.79 g, 3 mmol) in DMF (15 mL) was stirred in a 100° C. oil bath for 12 h. The cooled reaction mixture was poured into ice water. The solid was collected by filtration and purified by flash chromatography with CH2Cl2 as the eluent to afford compound 221 (1.6 g, 72%) as pink crystals; mp 114° C.; 1H NMR (CDCl3) δ 7.73-7.69 (m, 2H), 7.62-7.58 (m, 2H), 5.85-5.82 (m, 1H), 5.47-5.44 (m, 1H), 4.80-4.78 (m, 1H), 2.14-2.00 (m, 3H), 1.86-1.78 (m, 2H), 1.64-1.58 (m, 1H).
