Reaction Steps

Sodium borohydride (0.606 g, 16.03 mmol) was added portionwise to a suspension of 3-(6-(4-(4-chlorothiazol-2-yl)-4-oxobutyl)-1,3-dimethyl-2,4-dioxo-2,3,4,6-tetrahydro-1H-pyrrolo[3,4-d]pyrimidin-5-yl)benzonitrile (2.5 g, 5.34 mmol) in ethanol (53.4 mL) at 0° C. The reaction mixture was stirred for 15 minutes at 0° C., the quenched with water (25 mL) and extracted with DCM (3×50 mL). The combined organic fractions were dried over magnesium sulfate and evaporated under reduced pressure to afford the title compound.
