実験手順

This compound is prepared according to the procedure described in EXAMPLE 89 from 1 g of 5-chloro-3-(2-chlorophenyl)-1,3-dihydro-3-(dimethylamino)indol-2-one, 0.132 g of sodium hydride as a 60% dispersion in oil, 5 ml of DMF and 0.741 g of 4-nitrobenzyl bromide. Chromatography on silica using a DCM/hexane mixture (80/20; v/v) and then DCM as the eluent gives 1.32 g of the expected product after crystallization from a DCM/ iso ether mixture. M.p.=189°-193° C.
