Reaction Steps

A mixture of (±)-methyl-5-[[6-(1-hydroxy-3-(2-thienyl)propyl-1,3-benzodioxolyl]pentanoate (Compound 73, 35 mg, 0.093 mmol) and lithium hydroxide (0.37 ml of a 0.5N solution in H2O, 0.186 mmol) in THF (0.74 mL) was stirred at 23° C. for 16 hours. The mixture was acidified with 1N HCl and extracted with EtOAc. The organic portion was dried (MgSO4) filtered and concentrated in vacuo. Flash column chromatography (silica gel, 100% EtOAc) afforded 33.3 mg (99%) of the title compound. 1H NMR (300 MHz, CDCl3) δ 12.0 (brs, 1H), 7.14 (d, J=5.1 Hz, 1H), 7.00 (s, 1H), 6.93 (dd, J=3.3, 5.1 Hz, 1H), 6.83 (d, J=3.3 Hz, 1H), 6.59 (s, 1H), 5.91 (s, 2H), 4.87-4.92 (m, 1H), 2.97 (t, J=5.4 Hz, 2H), 2.43-2.47 (m, 2H), 2.32 (t, J=6.9 Hz, 2H), 1.86-2.18 (m, 2H), 1.44-1.64 (m, 5H).
