Procedure

A solution of 2-fluoro-4-methyl-6-nitrophenol D41 (400 mg, 2.337 mmol) (D41) in ethanol (50 mL) was hydrogenated using a Pd/C cartridge in the H-cube™ hydrogenator at 1 mL/min and full hydrogen. Evaporation gave 2-fluoro-4-methyl-6-aminophenol (250 mg, 1.771 mmol, 76% yield) as a fawn solid.
