Reaction Steps

cis-2-Benzyl-6-chloro-3a-methyl-2,3,3a,4,5,9b-hexahydro-1H-benzo[e]isoindole (18.60 mmol, 5.8 g) was dissolved in toluene and heated to reflux. Ethyl carbonochloridate (55.8 mmol, 5.33 ml, 6.06 g) was added dropwise and the reaction mixture left to stir at reflux for 2 hours. TLC and mass spec showed no starting material. Solvent removed in vacuo and crude material purified by silica column chromatography (eluting with 0-30% ethyl acetate:heptane) to give cis-ethyl 6-chloro-3a-methyl-3,3a,4,5-tetrahydro-1H-benzo[e]isoindole-2(9bH)-carboxylate (4.89 g), m/z=294.3 [M+H]+.
