Reaction Steps

At room temperature, 3-(5-Bromo-2-hydroxymethyl-phenylamino)-6-chloro-3-(3-chloro-benzyl)-1,3-dihydro-indol-2-one (100 mg, 0.137 mmol) was dissolved in 2 ml dried CH2Cl2. Then SOCl2 (49 mg, 0.333 mmol) was added slowly. After stirred for about half an hour, K2CO3 (84 mg, 0.612 mmol) and 1-piperazin-1-yl-ethanone (32 mg, 0.245 mmol) were added. This solution was stirred for about 2 h, then the solution was concentrated and the crude product was purified by Prep-HPLC to obtain 7 mg white solid rac-3-[2-(4-Acetyl-piperazin-1-ylmethyl)-5-bromo-phenylamino]-6-chloro-3-(3-chloro-benzyl)-1,3-dihydro-indol-2-one.
