HCID 587624232-{4-[2-(2-cyclopentyl-4,6-dioxotetrahydro-2H-pyran-2-yl)ethyl]-2-fluorophenyl)-2-methylpropanenitrile

Procedure

The desired product was prepared analogously to Step 5 of Example A(86), substituting 2-{4-[3-Cyclopentyl-4-(2,2-dimethyl-6-oxo-6H-[1,3]dioxin-4-yl)-3-hydroxy-butyl]-2-fluoro-phenyl}-2-methyl-propionitrile (1.23 g, 2.9 mmol) from Step 3 below in place of 1-{4-[3-Cyclopentyl-4-(2,2-dimethyl-6-oxo-6H-[1,3]dioxin-4-yl)-3-hydroxy-butyl]-2-fluoro-phenyl}-cyclopropanecarbonitrile. Yield: 0.614 g, 56%. 1H NMR (CDCl3) δ: 1.24-1.66 (m, 14H), 1.75-1.80 (m, 2H), 2.10 (p, J=9.35 Hz, 1H), 2.47-2.56 (m, 2H), 2.60 (d, J=5.56 Hz, 2H), 3.26 (d, J=3.28 Hz, 2H), 6.71-6.79 (m, 2H), 7.23 (t, J=8.24 Hz, 1H). MS (ESI): 370 (M−H).
