Procedure

To a solution of 112j (500 mg, 2.1 mmol) and 3,5-dibromo-1-methylpyridin-2(1H)-one (852 mg, 3.2 mmol) in dioxane (100 ml) was added Xantphos (58 mg, 0.1 mmol), Cs2CO3 (2.1 g, 6.4 mmol) and Pd2(dba)3 (110 mg, 0.1 mmol). The reaction mixture was stirred at 105° C. overnight. The mixture was cooled to RT, filtered, concentrated, and the crude product was purified through a silica gel column eluting with MeOH:DCM=0 to 1:5 to 112k (500 mg, 46.4%).MS: [M+H]+: 421
