Participants

Reaction Steps

A mixture of Example 84A (0.63 g, 2.13 mmol), iodoethane (0.68 mL, 8.52 mmol) and K2CO3 (1.47 g, 10.65 mmol) in acetone (50 mL) were stirred, and refluxed for 3 hours, and cooled. The solution was filtered, and dried with silica gel powder (10 g). 15% Ethyl acetate in hexanes (1 L) and 20% ethyl acetate in hexanes (1 L) were used to run flash chromatography. The title compound was obtained (320 mg, 46%). MS (DCI) m/z 324.07 (M+H)+; 1H NMR (300 MHz, CDCl3) δ ppm 1.39 (t, J=7.12 Hz, 3 H) 4.00 (q, J=7.12 Hz, 2 H) 4.46–4.55 (m, 2 H) 5.07–5.30 (m, 2 H) 5.88 (m, 1 H) 6.82 (dd, J=2.54, 0.85 Hz, 1 H) 6.93–6.96 (m, 2 H) 7.75–7.80 (m, 2 H) 7.94 (dd, J=5.42, 3.05 Hz, 2 H).
