Reaction Steps
Iodoethane (468 mg, 3.0 mmol) and powdered potassium carbonate (138 mg, 1.0 mmol) was added to a solution of ethyl 3-[4-(cyclopropylmethoxy)phenyl]-5-hydroxy-1-(3-methoxybenzyl)-1H-indole-2-carboxylate (Example 66, 120 mg, 0.25 mmol) in DMF (5 mL). The mixture was heated (50° C.) for 16 h and then cooled. The resulting mixture was diluted with ethyl acetate (50 mL), washed with water and brine, dried over anhydrous magnesium sulfate, and concentrated in vacuo. The residue was purified by preparative TLC using 4:1 ethyl acetate/hexane as the eluant, to afford 52 mg (42%) of the desired product. The product had: 1H NMR (300 MHz, acetone-D6) δ 7.42 (d, 1 H), 7.37 (d, 2 H), 7.19 (t, 1 H), 6.92-7.01 (m 4 H), 6.74-6.77 (m, 1 H), 6.64-6.68 (m, 2 H), 5.80 (s, 2 H), 4.13 (q, 2 H), 3.88-3.98 (m, 4 H), 3.69 (s, 3 H), 1.34-1.45 (m, 4 H), 1.04 (t, 3 H), 0.56-0.66 (m, 2 H), 0.34-0.44 (m, 2 H).
