Reaction Steps

A solution of methyl 2-(tert-butoxy)-2-(6-methyl-7-oxo-4-(p-tolyl)-6,7-dihydro-1H-pyrrolo[2,3-c]pyridin-5-yl)acetate (10 mg, 0.026 mmol) and 5-(bromomethyl)benzo[c][1,2,5]oxadiazole (22.28 mg, 0.105 mmol) in Acetonitrile (1 mL) was treated with cesium carbonate (34.1 mg, 0.105 mmol) and the resultant was stirred at 70° C. for 2 hours. The mixture was cooled to ambient temperature, water was added and the mixture was extracted with ethyl acetate. The combined extracts were washed with brine, dried over sodium sulfate, filtered and concentrated. The residue was used crude in the next step without further purification. LC/MS (m/z) ES+=515 (M+1).
