Versuchsvorschrift

1-(8-Chloro-2-methyl-1,2,3,4-tetrahydro-pyrido[4,3-b]indol-5-yl)-2-pyrimidin-4-yl-propan-2-ol (200 mg, 0.56 mmol) was dissolved in DCM (5 mL), and a drop of DMF was added. The solution was cooled to 0° C. and a solution of thionyl chloride (0.2 mL) in 1 mL DCM was added dropwise. The solution was stirred at RT for 30 min. and at RT for 2.5 h. Volatiles were evaporated under reduced pressure, the residue was basified with ice cold aqueous 1N NaOH (10 mL) and the product was extracted with EtOAc. The combined organic layer was washed with water and brine, dried over sodium sulfate and concentrated under reduced pressure. The residue was purified by HPLC to obtain 14 mg of product as the TFA salt. 1H NMR (CD3OD, TFA salt) δ (ppm): 9.18 (s, 1H), 8.80 (d, 1H), 8.0 (s, 1H), 7.80 (d, 1H), 7.58 (s, 1H), 7.25 (m, 2H), 4.75 (m, 1H), 4.40 (m, 1H), 3.90 (m, 1H), 3.60 (m, 1H), 3.20 (m, 2H), 3.10 (s, 3H), 2.05 (s, 3H).
