The downstream synthesis method of this compound is introduced below.
General procedure: Equimolar mixture of 6-chloro-5-(2-chloroethyl)-1,3-dihydro-2H-indol-2-one 1 (1.00mol) and the carbonyl compound (4i-x) (1.00mol) was stirred at RT in methanol (10mL) for 2h in presence of potassium carbonate (1.20mol). After completion, the reaction mass was filtered to remove inorganic salt, added methanol (10-20mL) and activated charcoal to the filtrate and stirred for 1hr. The crude product was filtered to remove charcoal, methanol was evaporated and cooled to 0-5C to get crude solid. Recrystallized using aqueous ethanol or methanol (Yield 60-70%).
