Reaction Steps

8-Chloro-2-methyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (1 g, 4.4 mmol) was dissolved in 10 mL of NMP. KOH (1.77 g, 31.78 mmol) was added at RT under nitrogen atmosphere and the reaction mixture was stirred for 5 min. 2-Bromomethyl-2-(4-chlorophenyl)-1,3-dioxolane (1.68 mg, 6.81 mmol) was added and the reaction mixture was heated at 100° C. for 3 h. Water was added and the product was extracted with EtOAc. The organic layer was washed with water, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was purified by silica gel chromatography eluting with 0-2% MeOH:DCM.
