Procedure

A mixture of 6-bromo-4,4-difluoro-3,4-dihydro-2H [1,8]naphthyridine-1-carboxylic acid amide (89.6 mg, 0.31 mmol), 3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyridine (92.3 mg, 0.46 mmol), K2CO3 (105 mg, 0.77 mmol) and bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium (II) (21.8 mg, 0.03 mmol) in 1 mL dioxane/water (9:1) is heated at 100° C. for 2 hrs. 30 mL of EtOAc is added. The mixture is washed with 2×10 mL of NaHCO3 and 1×10 mL brine. The organic phase is dried with MgSO4, filtered and concentrated. The residue is applied to a silica preparative TLC plate and purified (10% MeOH/CH2Cl2) to give 39.9 mg of the titled product.
