Reaction Steps
Aryl Bromide (Example 1, 100 mg, 0.25 mmol), aniline (27 uL, 0.30 mmol), Cs2CO3 (163 mg, 0.50 mmol) and Xantphos (43 mg, 0.075 mmol) were diluted with 4 mL of degassed THF. The resulting suspension was degassed for an additional 3 min then Pd2(dba)3 (23 mg, 0.25 mmol) was added giving a dark violet suspension which became dark yellow-orange within a few minutes. The mixture was then refluxed overnight, changing to cloudy orange as the aryl bromide was consumed. The next day the mixture was partitioned with water and ethyl acetate, separated, and the organic layer extracted twice with ethyl acetate. The combined organic layers were dried over MgSO4, filtered, concentrated and purified by preparative HPLC affording the desired product as a white powder. MS found for C21H18ClN3O2S as (M+H)+ 412.0, 414.0.
