Procedure

23.0 g (0.11 mol) of 2-amino-5-bromo-3,4-dimethylpyridine was mixed with 14.1 g (0.11 mol) of trimethylboroxin (TMB), 12.9 g (0.011 mol) of Pd(Ph3)4, 46.0 g (0.33 mol) of K2CO3 and 220 mL of DMF. The reaction mixture was heated under nitrogen at 115° C. for 18 hours. The reaction mixture was purified by silica gel column. The desired product was confirmed by MS.
