実験手順

To a t-butanol (20 ml) and H2O (5 ml) solution of 1-ethyl-3,3,5-trimethyl-2,4-dioxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepine-7-carbaldehyde (2.25 g) and 2-methyl-2-butene (3.25 ml) were added sodium dihydrogenphosphate (0.92 g) and sodium chlorite (2.081 g), and the mixture was stirred at room temperature overnight. Water was added to the reaction mixture, followed by extraction using ethyl acetate. The organic layer was dried with sodium sulfate, and was condensed under reduced pressure to give the title compound (0.98 g) as a white powder.
