2-氨基-3-甲氧基苯硫酚

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

实验步骤: Following the procedure described in Example 10 but substituting 2-amino-5-methylthiophenol for 2-amino-3-methoxythiophenol and substituting 2-methyl-p-benzoquinone for p-benzoquinone, a mixture of the title compounds were obtained. Chromatography on silica gel eluting with 10% EtOAc in CH2Cl2 afforded firstly 2,7-dimethyl-3H-phenothiazin-3-one, m.p. 177° C. were obtained

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

实验步骤: To a suspension of p-benzoquinone (3.0 g) in 15 ml methanol was added 2-amino-3-methoxythiophenol (2.2 g) dissolved in 10 ml methanol. The mixture was stirred at room temperature for 45 minutes and concentrated in vacuo. The residue was triturated with ether and filtered. The resulting dark solid was chromatographed on silica gel and eluted with EtOAc, to afford the desired compound, m.p. 206°-207°. concentrated in vacuo The residue was triturated with ether filtered The resulting dark solid was chromatographed on silica gel eluted with EtOAc
