Procedure

2-tert-Butoxy-2-(1-(4-chlorophenyl)-7-((4-hydroxytetrahydro-2H-pyran-4-yl)ethynyl)-3-methylnaphthalen-2-yl)acetic acid (80) was prepared by the method of Example 67 from ethyl 2-(7-bromo-1-(4-chlorophenyl)-3-methylnaphthalen-2-yl)-2-tert-butoxyacetate using 4-ethynyltetrahydro-2H-pyran-4-ol. 1H-NMR: 400 MHz, (CD3OD) δ: 7.76 (d, J=8 Hz, 7.68 (s, 1H), 7.57 (m, 3H), 7.42 (d, J=9 Hz, 1H), 7.30 (m, 2H), 5.16 (s, 1H), 3.85 (br m, 2H), 3.65 (br m, 2H), 2.60 (s, 3H), 1.92 (br m, 2H), 1.77 (br m, 2H), 0.98 (s, 9H). HPLC (Kinetex 2.6u, 50×4.6 mm, 2-100% MeCN/H2O+0.05% HOAc, 3.5 min run): tR (min)=2.41.
