Reaction Steps

A solution of N-(6-bromopyridin-2-yl)-2,2-dimethylpropanamide (2 g, 7.77 mmol, 1 eq.) in 25 ml of THF was cooled to −78° C. and n-BuLi (1.6 M, 9.72 ml, 15.55 mmol) was added dropwise. After 1 h, acetaldehyde (0.376 g, 8.55 mmol, 1.1 eq.) was added and the mixture was warmed to 0° C. within 1 h. The reaction was quenched with H2O, and diluted with EtOAc. The aqueous layer was separated and extracted with EtOAc. The organics were combined, dried over MgSO4 and concentrated. The crude material was purified by chromatography on silica gel to give N-[6-(1-hydroxyethyl)pyridin-2-yl]-2,2-dimethylpropanamide (1.45 g, 83% yield) as a white solid.
