Procedure

A 30 mL reaction vial was charged with 2-(4-iodophenyl)-N-(4-methyl-3-(5-methyl-4H-1,2,4-triazol-3-yl)thiophen-2-yl)acetamide (140 mg, 0.32 mmol), pyridin-4-ylboronic acid (60 mg, 0.48 mmol), sodium bicarbonate (100 mg, 1.2 mmol), DME (2 mL), and water (2 mL). The heterogeneous mixture was stirred vigorously under a stream of nitrogen for 5 minutes before Pd(PPh3)4 was added and the vial was sealed under its Teflon cap. The reaction mixture was heated to 90° C. for 3.25 h before being transferred to a microwave vial and being microwaved to 150° C. for 5 minutes. The reaction mix was concentrated under reduced pressure and the residue was partitioned between methylene chloride and a saturated aqueous solution of ammonium chloride. The organic solution was washed with brine and dried over sodium sulfate. The solution was concentrated under reduced pressure and the crude product was purified by column chromatography (3.5% MeOH/methylene chloride) Yield: 10.0 mg (8%).
