实验步骤: In the drybox, 51.0 mg (0.226 mmol) of (Me2CH)PH(O)(1-NMe2-4-Me—C6H3) from Example 32, 34.0 mg (0.151 mmol) of Pd(OAc)2 and 4.0 ml of toluene were loaded into a reactor (20 ml) equipped with a magnetic stir bar. The resulting mixture was stirred at room temperature for 1 h. Next, 216.0 mg (2.25 mmol) of NaOtBu, 314.0 mg (2.0 mmol) of PhBr and 135 mg (1.5 mmol) of HS-t-Bu were added into the mixture above, The resulting mixture was refluxed for 18 h. The reaction mixture was then cooled to room temperature, chromatographed on silicon gel using ethyl acetate/hexane (5% volume ratio) as eluant. The eluate was concentrated by rotary evaporation followed by high vacuum to yield 126 mg (51% yield) of t-butyl phenyl sulfide. It was >95% pure by 1H NMR and GC/MS. 1H NMR (500 MHz, CDCl3): δ7.43-7.42 (m, 2H), 7.22-7.19 (m, 3H), 1.17 (s, 9H) ppm. 13C NMR (125 MHz, CDCl3): δ137.4, 132.7, 128.5, 128.3, 30.9 ppm. (20 ml) equipped with a magnetic stir bar was refluxed for 18 h The reaction mixture was then cooled to room temperature chromatographed on silicon gel The eluate was concentrated by rotary evaporation
