実験手順

A solution of (S)-5′-amino-7-(2-fluoropyridin-3-yl)-2′,6′-dihydrospiro[chromeno[2,3-b]pyridine-5,3′-[1,4]oxazin]-3-ol (0.133 g, 0.352 mmol), potassium carbonate (0.194 g, 1.406 mmol), and neopentyl iodide (0.093 mL, 0.703 mmol) in 1.5 mL DMF was heated to 115° C. overnight. The reaction mixture was then diluted with 2-MeTHF and washed with water. The organics were dried over MgSO4 and concentrated. Purification of the crude residue by column chromatography [0-100% (9:1 EtOAc/MeOH)/DCM] gave (S)-7-(2-fluoropyridin-3-yl)-3-(neopentyloxy)-2′,6′-dihydrospiro[chromeno[2,3-b]pyridine-5,3′-[1,4]oxazin]-5′-amine (0.025 g, 0.056 mmol, 15.86% yield). MS m/z=449.20 [M+H]+. Calculated for C25H25FN4O3: 448.49.
