Procedure
To the solution of 159 g of 2-(2-isopropylaminopropyl)-5-pyridinol dihydrochloride in 1,000 ml of water, 163 g of sodium bicarbonate are added and the suspension evaporated. The residue is suspended in 453 ml of anhydrous ethanol at 60°, the suspension is filtered, the residue washed 3 times with 150 ml of anhydrous ethanol each and the combined filtrates are evaporated, to yield the 2-(2-isopropylaminopropyl)-5-pyridinol melting at 135°-138°.
