Methanol → HCID 21490914, compound

Participants

Reaction Steps

2.43 g (0.01 mol) of 4-chloro-5-n-butyl-6-methoxy-2-picolinic acid dissolved in 50 ml of methanol are hydrogenated in the presence of 300 mg of 5% strength palladium on charcoal. After the calculated amount of hydrogen has been taken up, the catalyst is filtered off and the filtrate is evaporated to dryness. Distillation of the residue in a bulb tube in a high vacuum at 120° yields 2-methoxycarbonyl-5-butyl-6-methoxy-pyridine of the formula ##STR14##
