Reaction Steps

TEA (400 μL, 2.86 mmol) followed by pivaloyl chloride (60 μL, 0.52 mmol) are added to 3-amino-2,4-difluoro-benzylamine (120 mg as HCl salt) in THF (10 mL) and the mixture is stirred at rt overnight. The reaction mixture is diluted with EtOAc and sat NaHCO3-solution, the organic layer is washed with water and brine, dried and concentrated to give the sub-title compound.
