A 250 mL three-necked round bottom flask fitted with magnetic stirrer and nitrogen inlet was charged with 5.0 g (30.6 mmol) of 2,6-diacetylpyridine and 60 mL of anhydrous isopropyl alcohol. To the stirred solution was added 1.16 g (3.06 mmol) of sodium borohydride in three equal portions. The initially colorless solution became yellow and warmed then slowly returned to pale yellow.
