Procedure
Synthesized using compound 54b (253 mg, 1.09 mmol) and cyclopropylmagnesium bromide (4.34 mL, 2.17 mmol, 0.5 M in THF) according to Method D. Crude product was purified by flash chromatography on silica-gel using a mixture of hexane/ethyl acetate (3:1) as eluent. Light yellow solid. Yield: 239 mg, 80%. 1H NMR (CDCl3, 500 MHz): δH (ppm)=0.39-0.54 (m, 2H), 0.60-0.72 (m, 2H), 1.22-1.29 (m, 1H), 4.04-4.14 (m, 1H), 7.42-7.60 (m, 5H), 7.86-7.92 (m, 3H), 8.04-8.08 (m, 1H), 8.77 (d, J=2.2 Hz, 1H); 13C NMR (CDCl3, 125 MHz): δC (ppm)=3.3, 3.9, 14.4, 60.6, 125.0, 125.5, 125.9, 126.1, 126.7, 127.7, 128.6, 129.1, 134.2, 137.8, 138.5, 147.8, 158.5, 171.4; MS (ESI): m/z=276.34 [M+H]+.
