Reaction Steps

To a solution of {5-[(S)-4-(2,3-Dihydro-[1,4]dioxino[2,3-b]pyridin-3-yl)-benzyl]-4,5,6,7-tetrahydro-thiazolo[5,4-c]pyridin-2-yl}-carbamic acid tert-butyl ester (prepared from Intermediate N according to General Method K) (50 mg, 0.10 mmol) in DCM (2 mL) with several drops MeOH is added 4M HCl in 1,4-dioxane (1.0 mL, 4.0 mmol) and the reaction stirred at rt for 16 h. The reaction is concentrated, suspended in Et2O and filtered to give the title compound 258. (LC/MS method 16: ES+ m/z 381.4 [M+H]+, Rt=0.36 m)
