실험 절차

A solution of 4-[3-(tert-butoxycarbonylamino)pyrrolidin-1-yl]-5-chloro-2-cyclopropylamino-3-fluorobenzoic acid ethyl ester (Example 3k, 2.00 g, 4.50 mmol) and aqueous sodium hydroxide (2.0N, 20 mL) in tetrahydrofuran (20 mL), and methanol (20 mL) is refluxed for 1 hour. The solution is partially concentrated in vacuo, acidified to pH 6, and extracted with chloroform. The combined organic extracts are dried over Na2SO4, filtered, and concentrated to give the title compound (1.70 g). 1H NMR (CDCl3): δ 7.71 (d, 1H), 4.91-4.82 (bd, 1H), 4.40-4.25 (m, 1H), 3.77-3.69 (m, 2H), 3.53-3.34 (m, 2H), 3.00-2.88 (m, 1H), 2.24-2.15 (m, 1H), 1.90-1.80 (m, 1H), 1.46 (s, 9H), 0.72-0.54 (m, 4H).
