실험 절차
To a solution of N-(6-cyclopropylpyridin-2-yl)pivalamide (4.25 gm, 19.49 mmol) in dioxane (34 ml) was added 9N HCl (34 ml). The mixture was stirred for 18 hours at 90° C. After cooling to 25° C., the pH of the reaction was adjusted with to achieve pH-9. The solution was diluted with ethyl acetate (200 ml) quantity and washed with saturated sodium bicarbonate. Next, the organic portion was dried over sodium sulfate and concentrated to get 2 gm (77.5% yield) clear oil.
