Trifluoroacetic acid → HCID 58762323, compound

Participants

Reaction Steps

Trifluoroacetic acid (0.07 mL, 0.88 mmol) was added to a solution of 6-{2-[3-Chloro-5-ethyl-4-(2-methoxy-ethoxymethoxy)-phenyl]-ethyl}-6-cyclopentyl-dihydro-pyran-2,4-dione (0.2 g, 0.44 mmol) dissolved in CH2Cl2 (4 mL). The reaction mixture was stirred for 2 hours at room temperature and then partitioned between H2O and EtOAc. The organic extracts were washed with brine, dried over Na2SO4 and concentrated to an oil. The oil was purified by flash column chromatography (0% to 30% EtOAc in hexanes) to give the title compound as a solid. (0.12 g, 75%). 1H NMR (400 MHz, CDCl3): δ 1.21 (t, J=7.6 Hz, 3H), 1.58-173 (br m, 8H), 1.92 (m, 2H), 2.26 (m, 1H), 2.57 (m, 2H), 2.65 (q, J=7.6 Hz, 2H), 2.76 (s, 2H), 3.43 (s, 2H), 5.47 (s, 1H), 6.81 (s, 1H), 6.95 (s, 1H). MS: C20H24O4Cl (M−H) 363.10.
