実験手順

This compound is prepared according to the procedure described in EXAMPLE 1 from 0.860 g of 3-amino-5-chloro-3-(2-chlorophenyl)-1,3-dihydroindol-2-one and 1 g of benzyl 4-chlorosulfonyl-3-methoxybenzoate. Chromatography on silica using a DCM/AcOEt mixture (99/1; v/v) as the eluent gives 1.38 g of the expected product, which is used as such in the next step.
