実験手順
The tert-butyl [1-(5-chloro-4-cyano-3-{6-[(dimethylamino)carbonyl]pyridin-3-yl}-2-ethoxyphenyl)ethyl]carbamate from the above step (0.04 g, 0.085 mmol) was treated with 4 M HCl in dioxane (4 mL) and stirred at room temperature for 1 hour. The reaction was concentrated in vacuo to give 5-{3-[1-aminoethyl]-5-chloro-6-cyano-2-ethoxyphenyl}-N,N-dimethylpyridine-2-carboxamide as a semi-solid residue (0.05 g, 100%). LCMS calculated for C19H22ClN4O2 (M+H)+: m/z=373.1. found: 373.1.
