Reaction Conditions

Reaction Steps

In a sealed tub was added ethyl 4-(thiazol-2-yl)benzoate (100 mg, 0.43 mmol), 4-methyliodobenzene (111 mg, 0.51 mmol), silver carbonate (236 mg, 0.86 mmol) and tetrakis(triphenylphosphine)palladium (0) (11.2 mg, 0.86 mmol). The flask was purged with nitrogen three times and then was added acetonitrile (1.8 mL). The mixture was stirred under Ar atmosphere for 12 h at 60° C. When the reaction completed, the inorganic solids were filtered on (Celite®) and the residue was washed several times with dichloromethane, then filtered and evaporated. Flash chromatography of the residue on silica gel (SiO2, hexane:ethyl acetate, 9:1) afforded 115.8 mg of ethyl 4-(5-(p-tolyl)thiazol-2-yl)benzoate as a white crystalline solid (84% yield). EM (IE): m/z (%): 323.1; (M+, 100). HRMS (ESI): calculated for C19H18NO2S: 324.1053. found: 324.1055.
