Under an argon atmosphere, 1,1-dimethylethyl 4-({[(2-bromo-4-chloro-6fluorophenyl)amino]carbonyl}amino)-1-piperidinecarboxylate (D7) (1.09 mmol, 0.493 g), 1,4-dioxane (4.4 ml), Pd2 dba3 (0.05 eq., 0.054 mmol, 50 mg), BINAP (0.055 eq., 0.059 mmol, 37 mg), NatBuO (1.5 eq., 1.63 mmol, 157 mg) were mixed together and heated to 80° C. under argon for 4 days. The reaction mixture was cooled to room temperature, quenched with water and the aqueous solution obtained was extracted with ethyl acetate. The solvent was evaporated and the crude was purified by MDAP. Fractions were collected and the solvent evaporated to yield the title compound, 15 mg, 3%, M+−H=368.
