Reaction Steps
A mixture of 5-ethynyl-2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (180 mg, 0.81 mmol), 3-bromofuran (100 mg, 0.68 mmol), dichlorobis(triphenylphosphine)palladium (II) (14 mg, 0.02 mmol) and TBAF.3H2O (642 mg, 2.0 mmol) was heated at 80° C. for 5 min by microwave After completion of reaction (monitored by TLC), the mixture was poured into water (10 mL) and extracted with EtOAc (3×10 mL). The organic layer was dried over sodium sulfate and concentrated under vacuum to obtain product, which was purified by reverse phase chromatography to obtain 10 mg of 5-furan-3-ylethynyl-2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole. 1H NMR, (CDCl3, freebase) δ (ppm): 7.70 (s, 1H), 7.50-7.4 (m, 2H), 7.20 (s, 1H), 7.10 (d, 1H), 6.55 (s, 1H), 3.68 (s, 2H), 3.0-2.90 (m, 4H), 2.60 (s, 3H), 2.40 (s, 3H).
