To 1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)-N-(5-methyl-6-(6-oxo-1,6-dihydropyridin-3-yl)pyridin-2-yl)cyclopropanecarboxamide (0.15 g, 0.35 mmol), (S)-4-(chloromethyl)-2,2-dimethyl-1,3-dioxolane (0.27 g, 1.8 mmol), and potassium carbonate (0.5 g, 3.5 mmol) was added N,N-dimethylformamide and the reaction mixture was heated to 100° C. overnight. The reaction was diluted with dichloromethane (20 mL) and washed with 1N hydrochloric acid (10 mL) and a saturated aqueous sodium bicarbonate solution (10 mL). The organics were dried over sodium sulfate and evaporated. The crude residue was purified by silica gel chromatography (eluting with 0-10% methanol in dichloromethane) to yield the product (47 mg, 27%). ESI-MS m/z calc. 499.16. found 500.2 (M+1)+. Retention time 1.53 minutes.
