Reaction Steps

1-(1,2,3,4-Tetrahydro-2,8-dimethylpyrido[4,3-b]indol-5-yl)-2-(pyridin-4-yl)butan-2-ol (0.5 g, 1.43 mmol) was dissolved in dry DCM (15 mL) and a drop of DMF was added. The solution was cooled to 0° C. and thionyl chloride (0.5 g, 4.29 mmol) diluted with dry DCM (2 mL) was added dropwise. Stirring was continued for 1 h at 0° C. and then at RT for 2 h. The solution was basified with saturated aqueous sodium bicarbonate and extracted with EtOAc (3×50 mL). The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by HPLC. 1H NMR (CDCl3, freebase) δ (ppm): 8.65 (d, 2H), 7.40 (d, 2H), 7.20 (s, 1H), 7.10 (d, 1H), 7.0 (d, 1H), 6.80 (s, 1H), 3.70 (s, 2H), 2.90 (m, 2H), 2.80 (m, 2H), 2.60 (s, 3H), 2.45 (m, 5H), 0.9 (t, 3H).
