Procedure

A solution of 2,6-difluorobenzoyl chloride (50 g, 283 mmol) in CH2 Cl2 (200 mL) was added rapidly dropwise to an ice water-cooled solution of 2-amino-2-methyl-1-propanol (63.1 g, 708 mmol) in CH2 Cl2 (400 mL). The resulting mixture was stirred at RT and monitored to completion by GLC, then was extracted twice with 10% HCl and once with sat aq NaHCO3. The organic phase was dried (MgSO4), and concentrated to afford 61.9 g N-(1,1-dimethyl-2-hydroxyethyl)-2,6-difluorobenzamide as a white solid.
