Reaction Steps

To a solution of 17.4 g (84.4 mmol) of 2,6-dichloro-4-methyl-pyridine-3-carboxylic acid in THF (340 ml) were added 10.6 ml (92.9 mmol) 3-fluorobenzylamine, 32.0 g (84.4 mmol) HATU and 35.0 ml (253.3 mmol) NEt3. The RM was then heated at 70° C. for 16. After dilution with EtOAc (350 ml) the mixture was washed with a 4M aq. NH4Cl sol., a 1M aq. NaHCO3 sol. and brine. The organic layer was dried over MgSO4 and concentrated in vacuo. Purification of the residue by CC (hexane/EtOAc 3:2) provided 19.5 g (62.3 mmol, 74%) 2,6-dichloro-N-(3-fluorobenzyl)-4-methyl-pyridine-3-carboxylic acid amide.
