2-氯-6-甲基苯硫酚

反应条件: temp:110.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of 4-(7-bromo-isoquinoline-1-yl)-piperazine-1-carboxylic acid, tert-butyl ester (0.5 g, 1.3 mmol), 2-chloro-6-methyl-thiophenol (0.206 g, 1.3 mmol), NatBuO (0.44 g, 4.5 mmol), Pd(PPh3)4 (74 mg, 0.065 mmol) in nBuOH (10 mL) was heated at 110° C., 3 h. The reaction mixture was filtered. The filtrate was concentrated and the residue was dissolved in ethyl acetate. The organic phase was washed with water (50 mL×3), separated and dried (MgSO4), filtered. The volatiles were evaporated and the residue was purified by flash column chromatography (SiO2, n-heptane: ethyl acetate 8:2) to give 530 mg of the title compound as colourless oil (yield 86.4%). 1H NMR (CDCl3) δ 8.05 (d, 1H), 7.65 (d, 1H), 7.20-7.45 (m, 5H), 7.15 (d, 1H), 3.26-3.40 (m, 4H), 3.10-3.20 (m, 4H), 2.5 (s, 3H), 1.38 (s, 9H). The reaction mixture was filtered The filtrate was concentrated the residue was dissolved in ethyl acetate The organic phase was washed with water (50 mL×3) separated dried (MgSO4) filtered The volatiles were evaporated the residue was purified by flash column chromatography (SiO2, n-heptane: ethyl acetate 8:2)
