Reaction Steps

trans-2-Benzyl-3a-methyl-6-(prop-1-en-2-yl)-2,3,3a,4,5,9b-hexahydro-1H-benzo[e]isoindole (0.359 mmol, 134 mg) was dissolved in toluene (1 ml). ACE-Cl (2.95 mmol, 325 μl) was added and the reaction mixture was heated in a microwave reactor at 160° C. for 15 minutes. MeOH (1 ml) was added and the mixture was again heated in a microwave reactor at 160° C. for 5 minutes. The resulting mixture was passed through an SCX cartridge and the resulting filtrate was concentrated in vacuo to give a crude residue that was purified by preparative-HPLC. To the pure fractions was added HCl in ether (1 ml) and the resulting solution was concentrated in vacuo to afford trans-3a-methyl-6-(prop-1-en-2-yl)-2,3,3a,4,5,9b-hexahydro-1H-benzo[e]isoindole hydrochloride (41 mg), MS m/z: 228.1 [M+H]+.
