Procedure

In a 10-mL microwave reaction vessel equipped with a magnetic stirring bar were placed 5-bromo-1-methyl-3-(6-(oxetan-3-yl)-5,6,7,8-tetrahydro-1,6-naphthyridin-2-ylamino)pyridin-2(1H)-one 219a (250 mg, 0.64 mmol), 10-[2-(acetoxymethyl)-3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-5-fluorophenyl]-4,4-dimethyl-1,10-diazatricyclo[6.4.0.02,6]dodeca-2(6),7-dien-9-one 230a (635 mg, 1.3 mmol), Pd(PPh3)4 (37 mg, 0.03 mmol) in 2 N Na2CO3 (2 mL) and 1,2-dimethoxyethane (2 mL). After the reaction mixture was stirred at 125° C. for 10 minutes, it was purified by flash chromatography (dichloromethane:methanol, 3:1) to give 12% (50 mg) of 292a as a solid.
