Temperature	100 °C

Reaction Steps

A mixture of methyl 3-chloro-6-fluorobenzo[b]thiophene-2-carboxylate 65a (0.613 mmol, 150 mg), cyclopropylboronic acid 65b (0.92 mmol, 79 mg), Pd(OAc)2 (0.09 mmol, 20 mg), SPhos (0.215 mmol, 88 mg), and K3PO4 (1.23 mmol, 0.26 g) in toluene (2 mL) was heated to 100° C. for 3 h in a sealed reaction vessel. The reaction was diluted with EtOAc and water. The organic layer was concentrated and purified by flash column chromatography (silica gel, 10% EtOAc/hexanes) to give compound 65c.
