The title compound was prepared according to the procedure in Example 5, step 3 using [2-(2-bromo-benzyl)-4,5-dimethyl-furan-3-yl]-(3-cyclopentyl-4-methoxy-phenyl)-methanone (2.82 g, 6.03 mmol) and 1M boron tribromide/CH2Cl2 (18.7 mL) in CH2Cl2. Purification on Biotage KP-Sil eluting with a 2, 5 & 10% EtOAc/pet. ether step gradient gave 1.36 g (50%) of the title compound. (DMSO-d6) δ 1.42-1.44 (m, 2 H), 1.58-1.72 (m, 4 H), 1.79 (s, 3 H), 1.87-1.92 (m, 2 H), 2.16 (s, 3 H), 3.17 (quintet, 1 H), 3.92 (s, 2 H), 6.85 (d, 1 H), 7.12-7.17 (m, 2 H), 7.29 (t, 1 H), 7.45 (dd, 1 H), 7.50-7.52 (m, 2 H), 10.31 (s, 1 H).
