Participants

Reaction Steps

3-Methyl-3,4-dihydronaphthalen-1(2H)-one was prepared in a similar manner as 6-bromo-3-methyl-3,4-dihydronaphthalen-1(2H)-one of Example 48, except using 3-methyl-4-phenylbutanoic acid. 1H NMR (400 MHz, CDCl3) δ 8.02 (d, J=7.9 Hz, 1H), 7.47 (dd, J=7.4, 7.4 Hz, 1H), 7.31 (dd, J=7.4, 7.4 Hz, 1H), 7.24 (d, J=7.4 Hz, 1H), 3.01-2.95 (m, 1H), 2.76-2.66 (m, 2H), 2.37-2.27 (m, 2H), 1.15 (d, J=7.2 Hz, 3H).
