실험 절차

Ethyl ((1S)-5-{3-[2-hydroxy-4-(4,5,6,7-tetrahydro-1,3-benzothiazol-2-yl)-phenoxy]-propoxy}-2,3-dihydro-1H-inden-1-yl)acetate (Example 165, 90 mg, 0.177 mmol) was dissolved in DMF (3 mL) after which Cs2CO3 (69.3 mg, 0.213 mmol) and water (3 drops) were added. Iodopropane (0.02 mL, 0.213 mmol) was added to the flask, and the reaction mixture was stirred at room temperature for 18 h. The mixture was then filtered and the filtrate purified by preparative HPLC giving the desired ester as a white solid (88.7 mg, 91%). 1H NMR (400 MHz, CD2Cl2): δ 7.47 (s, 1H), 7.37 (dd, 1H), 7.05 (d, 1H), 6.93 (d, 1H), 6.79 (s, 1H), 6.71 (dd, 1H), 4.23 (t, 2H), 4.19-4.13 (m, 4H), 4.03 (t, 2H), 3.50 (m, 1H), 2.94-2.78 (m, 6H), 2.70 (dd, 1H), 2.44-2.25 (m, 4H), 1.92-1.70 (m, 7H), 1.28 (t, 3H), 1.07 (t, 3H).
