A suspension of (1S,4R)-N-(4-chloro-2-((S)-4-cyclopropyl-1,1,1-trifluoro-2-hydroxybut-3-yn-2-yl)phenyl)-4,7,7-trimethyl-3-oxo-2-oxabicyclo[2.2.1]heptane-1-carboxamide (10, 1 g, 2.13 mmol) and 40% NaOH aqueous solution (20 mL) was stirred at 90-95° C. for 20 hours. Toluene (20 mL) was added and the layers were separated. The organic layer was washed with water (20 mL) and evaporated to dryness to give (S)-4-chloro-2-(4-cyclopropyl-1,1,1-trifluoro-2-hydroxybut-3-yn-2-yl) aniline (8).
