Reaction Conditions

Reaction Steps

Ammonium acetate (10.0 g, 130 mmol) followed by 4-methyl-3-(2-oxo-propyl)-pyridine-2-carboxylic acid tert-butylamide (1.61 g, 6.48 mmol) are added to acetic acid (20 mL) and the reaction mixture is heated at 110° C. for 3 h. The reaction mixture is cooled to RT and 20% NaOH is added until pH 6-7. The aqueous layer is extracted with DCM (3 times) and the combined organic layers are washed with brine, dried and evaporated under reduce pressure to furnish 4,6-dimethyl-[1,7]naphthyridin-8-ol (1.12 g, 99%) that is used as such.
