Instead of the starting material, that is, the compound S11, of Reference Example 43, tert-butyl 4-(aminomethyl)benzoate was used, and instead of (6R)-2-chlorophenyl 6-(5-chloro-2-methoxybenzyl)-3,7-dioxo-4-(2,4,6-trimethoxybenzyl)-1,4-diazepan-1-carboxylate, the compound S45 was used for a similar reaction as in Reference Example 43 to obtain tert-butyl 4-{[({(6R)-6-(5-chloro-2-methoxybenzyl)-3,7-dioxo-1,4-diazepan-1-yl}carbonyl)amino]methyl}benzoate (compound S47a).
