To a reaction vessel charged with (S,E)-4′-fluoro-7′-(2-fluoropyridin-3-yl)-2′-(2-(3-methyloxetan-3-yl)vinyl)-5H-spiro[oxazole-4,9′-xanthen]-2-amine (38 mg, 0.082 mmol) and Pd/C (5%) (30 mg, 0.082 mmol) was added EtOH (1.5 mL). The reaction mixture was purged with hydrogen gas for 5 minutes and then maintained under 1 atm of hydrogen gas for 4 hours. The mixture was filtered through celite and the derived filtrate concentrated to provide (S)-4′-fluoro-7′-(2-fluoropyridin-3-yl)-2′-(2-(3-methyloxetan-3-yl)ethyl)-5H-spiro[oxazole-4,9′-xanthen]-2-amine as white solid.
