Ethyl 2-(5-bromo-3-methyl-1-(trifluoromethylsulfonyloxy)naphthalen-2-yl)-2-(4-methoxybenzyl oxy)acetate (35) was prepared similarly to ethyl 2-(6-methoxy-3-methyl-1-(trifluoromethylsulfonyloxy)naphthalen-2-yl)-2-(4-methoxybenzyloxy)acetate of Example 32, using 1-(2-bromophenyl)propan-2-one as the starting material instead of 1-(3-methoxyphenyl)propan-2-one. 1H-NMR: 400 MHz, (CDCl3) δ: 8.11 (s, 1H), 8.01 (d, J=8.8 Hz, 1H), 7.85 (d, J=7.6 Hz, 1H), 7.40 (t, J=7.6 Hz, 1H), 7.23 (d, J=8.4 Hz, 2H), 6.81 (d, J=7.6 Hz, 2H), 5.61 (s, 1H), 4.62 (q, J=11.2 Hz, 2H), 4.26-4.15 (m, 2H), 3.75 (s, 3H), 2.62 (s, 3H), 1.18 (t, J=6.8 Hz, 3H).
