Reaction Steps
(2-bromophenyl)(methyl)sulfane (25 g, 123 mmol), Pd2dba3 (6.75 g, 7.38 mmol), S-Phos (6.06 g,14.77 mmol) and sodium tert-butoxide (17.74 g, 185 mmol) were placed in a dry 3 neck flask under N2. The reaction mixture was vacuum evacuated and back filled with N2 three times. Aniline (22.93 g, 246 mmol) and 500 mL toluene were added to the reaction mixture. The reaction mixture was refluxed for 18 hours. The crude reaction mixture was run through a silica gel plug and eluted with toluene. The toluene portion was concentrated down and subjected to a silica gel column by using 3-5% DCM in hexanes to yield desired product. (24 g, 111 mmol, 91%)
