Hydrochloric Acid → 4-(5-(3-Cyanophenyl)-1,3-dimethyl-2,4-dioxo-3,4-dihydro-1H-pyrrolo[3,4-d]pyrimidin-6(2H)-yl)-N-methoxy-N-methylbutanamide

Participants

Reaction Steps

T3P® (31.3 ml, 52.6 mmol) was added dropwise to a solution of N,O-dimethyllhydroxylamine hydrochloride (2.70 g, 27.6 mmol), DIPEA (18.39 ml, 105 mmol) and lithium 4-(5-(3-cyanophenyl)-1,3-dimethyl-2,4-dioxo-3,4-dihydro-1H-pyrrolo[3,4-d]pyrimidin-6(2H)-yl)butanoate (9.8 g, 26.3 mmol) in DMF (263 mL). The mixture was stirred at room temperature for 40 minutes and quenched with water (250 mL). The resultant precipitate was collected by filtration under reduced pressure to afford the title compound.
