Procedure:
N-chlorosuccinimide (215 g) was added during 10 minutes to a solution containing ethyl 3-amino-4-chlorobenzoate (108 g) and dimethyl sulphide (117 ml) in dichloromethane maintaining below 0° C. Triethylamine (80 ml) was added and after 20 minutes further additions of dimethyl sulphide (117 ml), N-chlorosuccinimide (215 g) and triethylamine (80 ml) were made. After 0.5 hours additional triethylamine (280 ml) was introduced, the mixture heated under reflux conditions overnight and evaporated. Ether was added and this was washed with water, dilute sodium bicarbonate, dried (magnesium sulphate) and evaporated. Purification by chromatography, eluting with ethyl acetate/petroleum ether gave ethyl 3-amino-4-chloro-2-methylsulphenylmethylbenzoate (47.6 g), NMR (CDCl3) 1.45 (t,3H), 2.1 (s,3H), 4.1 (s,2H), 4.3 (q,2H), 4.7 (s,2H), 7.2 (m,2H).

Procedure:
To a solution of ethyl 3-(3,4-methylenedioxyphenyl)-1-oxoindene-2-carboxylate (100 mg, 0.31 mmol) in THF (2 ml) under an argon atmosphere at 0° C. was added a solution of freshly prepared 3-methoxyphenyl magnesium bromide (0.31 mmol). After stirring for 15 min, additional 3-methoxyphenyl magnesium bromide (0.06 mmol) was added. Stirring was continued for 45 min, at which time thin layer chromatographic analysis indicated that the reaction was incomplete. Additional 3-methoxyphenyl magnesium bromide (0.12 mmol) was added. After stirring for 2 h more, the mixture was partitioned between 3M HCl and EtOAc. The organic extract was washed successively with H2O, 5% aqueous NaHCO3, H2O and saturated aqueous NaCl. The solvent was removed in vacuo, and the residue was purified by flash chromatography, eluting with 15% EtOAc/hexanes to afford the title compound (150 mg, 100%).
