実験手順

4-(2-Fluoropyridin-4-yl)-1-{2-[4-(trifluoromethoxy)phenoxy]ethyl}-1H-pyrrolo[3,2-c]pyridine-2-carboxylic acid potassium salt (25 mg, 0.050 mmole) was taken up in pyridine (0.3 mL) in a screw cap vial. To this was added ethanolamine (0.015 mL, 0.250 mmole). The vial was capped then heated to 120° C. After stirring overnight ethanolamine (0.015 mL, 0.250 mmole) was added and heating continued. After stirring overnight the mixture was cooled to RT and concentrated. The crude material was taken up in DMSO and acidified with TFA. The resulting solution was purified by preparative reversed-phase HPLC (30×100 mm Phenomenex AXIA-Gemini-NX, 5%-95% CH3CN/water containing 0.1% TFA over 18 min at 50 mL/min) to give the title compound (16 mg, 52%) as a yellow solid. 1H NMR (499 MHz, DMSO): δ 8.58 (d, J=5.9 Hz, 1 H); 8.04 (d, J=6.7 Hz, 1 H); 7.95 (d, J=6.0 Hz, 1 H); 7.73 (s, 1 H); 7.66 (s, 1 H); 7.43 (d, J=6.6 Hz, 1 H); 7.23 (d, J=8.6 Hz, 2 H); 6.90 (d, J=8.8 Hz, 2 H); 5.13-5.04 (m, 2H); 4.39-4.35 (m, 2 H); 3.68 (m, 2 H); 3.49 (bs, 2 H). HRMS (ESI) calc (M+H)+=503.1537. found 503.1529.
