Reaction Steps

A solution of 2-(5-benzyloxy-biphenyl-2-yloxy)-2-methyl-propionic acid ethyl ester (3.58 g, 7.63 mmol maximum) in ethanol (75 mL) was treated with 5% Pd/C (3.0 g) and hydrogen (balloon, room temperature, 16 h). The mixture was filtered and concentrated to a viscous colorless oil (2.44 g, 107%): 1H NMR (400 MHz, CDCl3) δ1.25 (t, 3H, J=7.1 Hz), 1.27 (s, 6H), 4.20 (q, 2H, J=7.3 Hz), 4.95 (brs, 1H), 6.67 (dd, 1H, J=3.4, 8.8 Hz), 6.81 (d, 1H, J=3.4 Hz), 6.88 (d, 1H, J=8.8 Hz), 7.30 (dt, 1H, J=1.5, 7.3 Hz), 7.37 (dt, 2H, J=1.5, 7.3 Hz), 7.52 (dd, 2H, J=1.5, 6.8Hz).
