methyl 2-chloro-5-{[(6E)-6-(5-chloro-2-methoxybenzylidene)-3,7-dioxo-1,4-diazepan-1-yl]sulfonyl}benzoate → Methyl 4-[(6-benzyl-3,7-dioxo-1,4-diazepan-1-yl)sulfonyl]benzoate

Participants

Reaction Steps

4-[(6-benzyl-3,7-dioxo-1,4-diazepan-1-yl)sulfonyl]benzoic acid, synthesized by using 4-(tert-butoxycarbonyl)benzenesulfonamide instead of the starting material compound of Example 198, that is, 3-(tert-butoxycarbonyl)benzenesulfonamide for the similar procedure as in Example 198, was used instead of the starting material of Example 208, that is, the compound 196, for the similar procedure as with Example 208 to obtain the title compound.
