Participants

Reaction Steps

To a solution of 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indole-7-carboxamide (500 mg, 1.1 mmol) in dioxane (12 mL) and H2O (4 mL) was added 2-bromo-1,3-thiazole-5-carbaldehyde (634 mg, 3.3 mmol), potassium carbonate (898 mg, 8.8 mmol) and tetrakis(triphenylphosphine)palladium(0) (210 mg, 0.181 mmol). Reaction was run in the microwave at 150° C. for 20 min. Aqueous work-up performed to give crude product. The reaction was then repeated in the microwave at 150° C. for 30 min to give 3-[1-(ethylsulfonyl)-4-piperidinyl]-5-(5-formyl-1,3-thiazol-2-yl)-1H-indole-7-carboxamide.
