Participants

Reaction Steps

3-Methyl-4-phenylbutanoic acid was prepared in a similar manner as 4-(2-methoxy-phenyl)-3-methyl-butyric acid of Example 32 except using 1-phenylpropan-2-one. 1H NMR (400 MHz, CDCl3) δ 7.31-7.14 (m, 5H), 2.65 (dd, J=13.3, 6.7 Hz, 1H), 2.53 (dd, J=13.3, 7.4 Hz, 1H), 2.38 (dd, 14.9, 5.5 Hz, 1H), 2.28 (app. sext. J=6.7 Hz, 1H), 2.17 (dd, 14.5, 7.8 Hz, 1H), 0.98 (d, J=6.6 Hz, 3H).
