Procedure

A solution of {2-Hydroxy-1-[3-(tetrahydro-pyran-2-yloxy)-octyl]-2,3,3a,4,9,9a-hexahydro-1H-cyclopenta[b]naphthalen-5-yloxy}-acetic acid (94 mg, 0.2 mmol), trifluoroethylamine (54 mg, 0.6 mmol) and DIPEA (104 μl, 0.6 mmol) in DMF (2 ml) was treated with HATU and stirred 24 hr at RT. The reaction mixture was diluted with MTBE and washed with saturated sodium bicarbonate solution and brine, dried over sodium sulfate and concentrated under vacuum. The residue was purified by silica gel chromatography. This resulting material was dissolved in MeOH (4 ml), treated with Amberlite IR120H and stirred 24 hr. The reaction mixture was filtered and concentrated to yield 2-[2-hydroxy-1-(3-hydroxy-octyl)-2,3,3a,4,9,9a-hexahydro-1H-cyclopenta[b]naphthalen-5-yloxy]-N-(2,2,2-trifluoro-ethyl)-acetamide (46 mg) as an oil. 1HNMR (400 MHz, CDCl3) δ 7.06 (d, 1H, J=7.6); 6.80 (d, 1H, J=7.2); 6.63 (d, 1H, J=8.0); 4.86 (quint., 1H, J=6.4); 4.60 (s, 2H); 3.7-3.8 (m, 1H); 3.55-3.65 (m, 1H); 2.85-2.95 (ddd, 1H); 2.70-2.80 (dd, 1H); 2.50-2.60 (ddd, 1H); 2.40-2.50 (dd, 1H); 2.15-2.3 (m, 2H); 1.75-1.95 (m, 2H); 1.24-1.70 (m, 17H); 1.20 (d, 3H, J=6.4); 0.85-0.95 (m, 8H); MS: m/z 494 [M+Na]+
