実験手順

To a solution of ethyl ((1S)-5-{3-[(1-methyl-1H-indol-5-yl)oxy]propoxy}-2,3-dihydro-1H-inden-1-yl)acetate (51 mg, 0.13 mmol) (Example 48) in THF (1.8 mL) was added LiOH.H2O (6 mg, 0.15 mmol) in water (0.6 mL). The mixture was stirred for 12 h at rt, then the reaction mixture was concentrated under reduced pressure and the residue suspended in a small volume of water. The pH was adjusted to below 3 with HCl (1 N aqueous solution), and the aqueous layer was extracted with EtOAc. The organic layer was dried, filtered, and concentrated under reduced pressure to give 44 mg (93%) of the title compound as a solid. 1H NMR (400 MHz, CDCl3): δ 7.10 (d, 1H), 7.05-6.96 (m, 2H), 6.93 (d, 1H), 6.81 (dd, 1H), 6.72 (s, 1H), 6.65 (dd, 1H), 6.32 (d, 1H), 4.18-4.00 (m, 4H), 3.69 (s, 3H), 3.52-3.40 (m, 1H), 2.92-2.65 (m, 3H), 2.42-2.24 (m, 2H), 2.22-2.10 (m, 2H), 1.78-1.62 (m, 1H); LC-MS RT=3.45 min, (M+H)+ 380.1.
