Participants

Reaction Steps

To a microwave vial was added 5-(5-acetyl-2-methylphenyl)-1-(2,2-dimethylpropyl)-3-methyl-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (15-7) (30 mg, 0.085 mmol) and thiomorpholine 1,1-dioxide (17 mg, 0.13 mmol) were added under nitrogen and dissolved in toluene (0.43 ml). Titanium(IV) chloride (10 mg, 0.05 mmol) was added to the solution and the reaction was allow to stir at room temperature overnight. Sodium cyanoborohydride (8 mg, 0.12 mmol) was then added and allowed to stir for 1 hour. The reaction was diluted with methanol, and passed through a syringe filter. The solution was purified using reverse phase chromatography (10-100%, 0.1% TFA in H2O/Acetonitrile) and the desired fractions were collected and concentrated to produce 1-(2,2-dimethylpropyl)-5-{5-[(1R)-1-(1,1-dioxidothiomorpholin-4-yl)ethyl]-2-methylphenyl}-3-methyl-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (36-1). HRMS (M+H)+: observed=471.2421, calculated=471.2424.
