Reaction Steps

A vial charged with (R)-4-(2-amino-3′-fluoro-2′-(pyrimidin-5-yl)-5H-spiro[oxazole-4,9′-xanthene]-7′-yl)-2-methylbut-3-yn-2-ol (0.050 g, 0.116 mmol) and 10% Pd/C (1.236 mg, 0.012 mmol) was taken up in 5 mL MeOH thoroughly degassed then placed under 50 psi H2 overnight. The reaction mixture was filtered through celite and concentrated in vacuo to provide an off white solid. Purification of the crude residue by column chromatography [0-80% (9:1:0.1—CH2Cl2:MeOH:NH4OH)/CH2Cl2] gave (R)-4-(2-amino-3′-fluoro-2′-(pyrimidin-5-yl)-5H-spiro[oxazole-4,9′-xanthene]-7′-yl)-2-methylbutan-2-ol. MS m/z=435.0 [M+H].
