Procedure
An ethereal solution of methyl magnesium bromide (3 mol/l) (546 ml) was added dropwise to a solution of 6-formyl-2-pyridinecarboxamide (61.5 g) in tetrahydrofuran (900 ml) at 0°-13° C. with stirring. After the mixture was stirred at the same temperature for 2 hours and cold water was dropped to the reaction mixture under ice-cooling. To the mixture was added ethyl acetate and adjusted to pH 7 with 6N-hydrochloric acid. The separated organic layer was washed with brine, dried over magnesium sulfate and evaporated in vacuo to give 6-(1-hydroxyethyl)-2-pyridinecarboxamide (63.2 g) as an oil.
