The reaction was diluted with dichloromethane and extracted with water. The product was obtained as a slightly yellow solid (0.5298 g, 28%) after evaporation of the dichloromethane layer, and was used for the next step without further purification. 1H NMR (400 MHz, CDCl3): 2.09 (2H, m), 3.93 (2H, t, J=5.6 Hz), 4.10 (2H, t, J=5.6 Hz), 4.51 (11H, s), 6.25 (1H, d, J=5.5 Hz), 7.32 (1H, t, J=7.4 Hz), 7.56 (1H, t, J=8.2 Hz), 7.90 (1H, d, J=8.4 Hz), 7.93 (1H, d, J=8.4 Hz), 8.36 (1H, d, J=5.3 Hz).
