Synthesized using compound 44a (150 mg, 0.70 mmol), CDI (570 mg, 3.52 mmol) and acetonitrile (9 mL) according to Method E. Crude product was purified by flash chromatography on silica-gel using a mixture of hexane/ethyl acetate (3:1) as eluent. White solid. Yield: 116 mg, 54%. 1H NMR (CDCl3, 500 MHz): δH (ppm)=1.04 (t, J=7.4 Hz, 3H), 2.01-2.15 (m, 1H), 2.22 (dt, J=14.3, 7.2 Hz, 1H), 5.92 (t, J=7.1 Hz, 1H), 7.09 (dd, J=1.6, 0.6 Hz, 1H), 7.41-7.51 (m, 4H), 7.75-7.80 (m, 2H), 7.98-8.03 (m, 2H), 8.17-8.19 (m, 1H), 8.74-8.77 (m, 1H); 13C NMR (CDCl3, 125 MHz): δC (ppm)=9.8, 28.7, 79.8, 117.0, 120.3, 126.9, 128.8, 129.3, 130.8, 132.3, 135.0, 137.0, 138.6, 148.0, 148.3, 158.0; MS (ESI): m/z=308.30 [M+H]+.
