To a solution of 1-{4-[3-Cyclopentyl-4-(2,2-dimethyl-6-oxo-6H-[1,3]dioxin-4-yl)-3-hydroxy-but-1-ynyl]-2-fluoro-phenyl}-cyclopropanecarbonitrile (1.0 g, 2.4 mmol) from Step 5 above dissolved in EtOH (20 mL) was added Pd(OH)2/C (20% wt dry basis, 100 mg) and the reaction was stirred under a hydrogen atmosphere for 6 hours. The palladium catalyst was removed by filtration, and the solvent removed by rotary evaporation. The resulting oil was used without further purification (1.02 g, 99% yield).
