2-氟-N-甲基苯甲酰胺

反应条件: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of 5-ethynyl-2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (268 mg, 1.2 mmol), 4-bromo-2-fluoro-N-methyl-benzamide (230 mg, 1.0 mmol), dichlorobistriphenyl phosphinepalladium (II) (21 mg, 0.03 mmol) and TBAF.3H2O (945 mg, 3.0 mmol) were added to a reaction vessel and the contents heated at 80° C. for 5 min in microwave. After completion of reaction (as monitored by TLC & LCMS), the reaction mixture was poured into water (25 mL) and the compound extracted with EtOAc (3×60 mL). The combined organic layers were dried over sodium sulfate, concentrated under vacuum and purified by reverse phase chromatography to obtain 22 mg of 4-[2-(2,8-dimethyl-1,2,3,4-tetrahydro-pyrido[4,3-b]indol-5-yl)-5-yl)-2-fluoro-vinyl]-2-fluoro-N-methyl-benzamide and 63 mg of product. 1H NMR (CD3OD, oxalate salt) δ (ppm): 8.30 (m, 1H), 8.80 (t, 1H), 7.50 (t, 1H), 7.38-7.24 (m, 3H), 7.10 (d, 1H), 6.80 (m, 2H), 3.60 (m, 2H), 3.25 (m, 2H), 3.04 (s, 3H), 2.96 (d, 3H), 2.82 (s, 3H), 2.40 (s, 3H). 3H2O (945 mg, 3.0 mmol) were added to a reaction vessel After completion of reaction (as monitored by TLC & LCMS) the compound extracted with EtOAc (3×60 mL) The combined organic layers were dried over sodium sulfate concentrated under vacuum purified by reverse phase chromatography
