Reaction Steps
2-t-Butoxycarbonylamino-3-ethylpyridine (4.9 g, 19.8 mmol) was dissolved in 90 ml of 3N HCl/Acetic acid and stirred for two hours. The solution was neutralized with 2N NaOH to pH 7 and then extracted with ethyl acetate (2×400 ml). The organics were dried over magnesium sulfate and concentrated giving 2.3 g (95%) of a yellowish solid. This solid was used in the next reaction without further purification.
