Reaction Steps

62.41 g of tert-butyl 5-iodo-2,3-dioxo-2,3-dihydroindole-1-carboxylate are dissolved in dried THF, and 18.98 ml of 2,3-dihydro-1H-isoindole are added. The mixture is stirred at 25° C. for 30 min, evaporated to dryness in vacuo, and the residue is triturated with petroleum ether, filtration gives 82.3 g of tert-butyl {2-[2-(1,3-dihydroisoindol-2-yl)-2-oxoacetyl]-4-iodophenyl}-carbamate (beige solid);
