Versuchsvorschrift
A solution of 3-(3-allyl-4-hydroxyphenyl)-2-methyl-2-phenoxy-propionic acid ethyl ester(330 mg, 0.97 mmol) in absolute ethanol (5 mL) was treated with 5% Pd/C and then the mixture was evacuated thee times with N2. The reaction mixture was hydrogenated at 1 atm with an H2-filled balloon for 24 h before filtering the mixture over celite and rinsing with ethanol. The product was used without further purification. 1H NMR (400 MHz, CDCl3) δ 7.22 (t, J=7.6 Hz, 2H), 7.99–6.95 (m, 3H), 6.82 (m, 2H), 6.68 (d, J=8.0 Hz, 1H), 4.20 (q, J=6.8 Hz, 2H), 3.24 (A of AB, J=13.6 Hz, 1H), 3.08 (B of AB, J=13.6 Hz, 1H), 2.55 (t, J=7.6 Hz, 2h), 1.62 (sextet, J=7.6 Hz, 2H), 1.41 (s, 3H), 1.23 (t, J=6.8 Hz, 3H), 0.96 (t, J=7.2 Hz, 3H).
