Participants

Reaction Steps

A mixture of 0.1 g of benzyl 4-{6-[(acetylamino)methyl]-3-(3,4-dimethoxybenzyl)-2,4-dioxo-3,4-dihydroquinazolin-1(2H)-yl}piperidine-1-carboxylate obtained in stage 5.6, 0.016 g of ammonium formate and 0.018 g of Pd/C (10%) in 2 ml of EtOH purged beforehand with nitrogen is irradiated under a microwave field at 80° C. for 30 min. The mixture is filtered and the filtrate is evaporated under reduced pressure to give 0.077 g of the expected product.
