Reaction Steps

Enantiomer 2 of (cis)-tert-butyl 4-(2-([1,2,4]triazolo[4,3-a]pyridin-3-yl)-6-fluoroquinolin-8-yloxy)-5-fluoroazepane-1-carboxylate (Example 90, Step D; 0.119 g, 0.240 mmol) was dissolved in CHCl3 (2.4 mL). HCl (2.40 mL, 9.61 mmol, 4.0M Dioxane) was added and the mixture was stirred at ambient temperature for 3 hours. The mixture was filtered through a polypropylene filter and washed with CH2Cl2 and then Et2O, then slurried in hexanes and dried carefully in vacuo to provide 0.095 g of the desired product as a white solid (85%). MS ESI (+) m/z 396.1 (M+1) detected.
