Phenylacetyl chloride → 1-(3-(4-methoxybenzyl)-8,9-dihydro-3H-pyrazolo[3,4-c][2,7]naphthyridin-7(6H)-yl)-2-phenylethanone

Participants

Reaction Steps

To a mixture of 3-(4-methoxybenzyl)-6,7,8,9-tetrahydro-3H-pyrazolo[3,4-c][2,7]naphthyridine (0.164 g, 0.56 mmol) and 2-phenylacetyl chloride (0.96 mL, 0.724 mmol) was added 1,2-dichloroethane (2 mL). The reaction mixture was stirred at room temperature for 16 hours. The crude reaction mixture was washed with saturated aqueous sodium bicarbonate (20 mL) and brine (20 mL). The organic extract was dried over Na2SO4 and concentrated under reduced pressure to give the desired product, 1-(3-(4-methoxybenzyl)-8,9-dihydro-3H-pyrazolo[3,4-c][2,7]naphthyridin-7(6H)-yl)-2-phenylethanone as a brown oil (0.230 g, 100%). LCMS [M+H]: 413.
