Procedure

Hydrazine (9 mg, 0.28 mmol) was added to a solution of 2-(3-Phthalimido-n-prop-1-yl)-cis-2,3,3a,4,9,9a-hexahydro-1H-benz[f]isoindole (50 mg, 0.14 mmol) in 1 mL of ethanol, and the mixture was refluxed for 6 hours. The mixture was cooled to room temperature, and 5 mL of diethyl ether was added with stirring. After 30 minutes, a white solid had precipitated. The solid was collected by filtration, rinsed with diethyl ether, then stirred in 10 mL of chloroform. The solids were filtered and washed with chloroform. The filtrate was concentrated to yield 20 mg of a colorless oil as product. Yield=63%. NMR (300 MHz, CD3OD) δ7.09-7.05 (m, 4H), 3.03-2.97 (m, 2H), 2.77-2.70 (dd, 2H, J=6 Hz, 14 Hz), 2.68-2.58 (m, 4H), 2.50-2.44 (dd, 2H, J=5 Hz, 14 Hz), 2.30 (t, 2H, J=7 Hz), 1.82 (t, 2H, J=7 Hz), 1.61 (tt, 2H, J=7 Hz, 8 Hz, 7 Hz).
