실험 절차

To a solution of toluene-4-sulfonic acid 4-isopropoxy-6-(1-methyl-1H-pyrazol-3-ylcarbamoyl)-2,3-dihydro-benzofuran-2-ylmethyl ester (216a) (84 mg, 0.17 mmol) in THF (2 mL) was added dimethyl amine hydrochloride (190 mg) and triethylamine (0.4 mL). The mixture was heated at 50° C. for 2 days, then concentrated, and purified by reverse phase HPLC to give a white solid (6 mg, 10% yield). 1H NMR (400 MHz, CDCl3) δ 8.94 (s, 1 H) 7.25-7.32 (m, 1 H) 7.04 (s, 1 H) 6.90 (d, J=1.01 Hz, 1 H) 6.84 (d, J=2.27 Hz, 1 H) 5.03-5.14 (m, 1 H) 4.61-4.71 (m, 1 H) 3.81 (s, 3 H) 3.29 (dd, J=16.42, 9.35 Hz, 1 H) 2.75-2.92 (m, 2 H) 2.60-2.70 (m, 1 H) 2.47 (s, 6 H) 1.34 (d, J=6.06 Hz, 6 H); LCMS for C19H26N4O3 m/z 359.20 (M+H+).
