実験手順
Enantiomer 1 of trans-tert-butyl 4-(2-([1,2,4]triazolo[4,3-a]pyridin-3-yl)-6-fluoroquinolin-8-yloxy)-5-fluoroazepane-1-carboxylate (Peak 1 from Example 91, Step E; 0.210 g, 0.424 mmol) was dissolved in CHCl3 (4.3 mL). To this solution was added HCl (4.24 mL, 17.0 mmol, 4.0M Dioxane) and the mixture was stirred at ambient temperature for 3 hours. The mixture was filtered through a polypropylene filter and washed with CH2Cl2 and Et2O, slurried in hexanes and then dried carefully in vacuo to provide the desired product as white solid. MS ESI (+) m/z 396.1 (M+1) detected.
