Pottasium tert-butoxide (0.03 g, 0.27 mmol) was added to a suspension of 6-bromo-1H-pyrrolo[3,2-b]pyridin-2(3H)-one (preparation 16c, 0.87 g, 4.1 mmol) in dimethylsulphoxide (4 mL) and, after stirring for 10 minutes at room temperature, the mixture was heated to 40-45 C and methyl acrylate (1.14 mL, 12.71 mmol) was added dropwise over 60 minutes. After the addition, the mixture was stirred for 2 hours and then further potassium tert-butoxide (1.4 g, 12.21 mmol) was added portionwise over 30 minutes keeping the temperature below 50 C. The mixture was then heated to 100 C and stirred for 2 hours. Water (20 mL) was added and heating was continued at 85 C for 2 hours and then the mixture was left to cool overnight. Ethyl acetate was added and the organic layer was washed with water, brine, dried (MgSO4) and evaporated to give the title compound (0.60 g, 50%) as a white solid. LRMS (m/z): 293/295 (M-1)+. 1H-NMR delta (CDCl3): 2.14 (m, 2H), 2.27 (m, 2H), 2.73 (m, 2H), 3.01 (m, 2H), 7.40 (d, J=1.5 Hz, 1H), 8.29 (d, J=1.5 Hz, 1H), 8.44 (br s, 1H).
