Reaction Steps
Methyl 2-bromoisonicotinate (3.39 g, 15.69 mmol), 4-chlorophenylboronic acid (3.68 g, 23.54 mmol), potassium carbonate (3.25 g, 23.54 mmol) and PdCl2 (dppf) (0.341 g, 0.47 mmol) were mixed in methanol (30 mL) in two separate 20 mL microwave vials. The vials were capped and heated at 100° C. for 10 min in a single node microwave reactor. Water and DCM were added and the phases were separated. The water phase (pH 9) was extracted with DCM and the combined organic phase washed with brine, passed through a phase separator and evaporated to yield an orange solid. The solid was dissolved in MTBE, then HCl (4 M in dioxane) was added to give crude methyl 2-(4-chlorophenyl)isonicotinate hydrochloride (4.3 g). MS m/z 248 (M+H)+
