To a flask containing N-(6-(1-(2-aminoethyl)-6-oxo-1,6-dihydropyridin-3-yl)-5-methylpyridin-2-yl)-1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropanecarboxamide (36 mg, 0.08 mmol), ethyl chloroformate (10 mg, 0.09 mmol), and triethylamine (32 μL, 0.23 mmol) was added N,N-dimethyl formamide (1 mL) and the reaction mixture was stirred at room temperature overnight. The reaction mixture was filtered and purified by reverse-phase preparative liquid chromatography to give the product (11 mg, 25%). ESI-MS m/z calc. 540.18. found 541.7 (M+1)+. Retention time 1.72 minutes.
