Reaction Steps

10% Palladium on carbon (0.52 g) was added to a methanol solution (50 ml) of 7-[4-(1,3-dioxo-1,3-dihydroisoindol-2-yl)but-1-ynyl]-1-ethyl-3,3,5-trimethyl-1,5-dihydrobenzo[b][1,4]diazepine-2,4-dione (2.2 g). The mixture was subjected to catalytic reduction at room temperature under normal pressure. The catalyst was removed by celite filtration, followed by concentration under reduced pressure to give the title compound (1.93 g) as a brown solid.
