Reaction Steps

To a solution of (2S)-2-amino-3-(piperidin-4-yl)-N-(quinolin-3-yl) propanamide LXXVI in a mixture of methanol (15 mL) and water (5 mL) was added Et3N (0.60 mL, 4.24 mmol) and CuSO4 (20 mg). The mixture was treated at 0° C. with freshly prepared solution of triflic azide (5.9 mmol) in DCM (10 mL). The mixture was stirred at r.t. for 48 h. The solvent was evaporated under reduced pressure and dissolved in EtOAc, washed with satd. aq. NaHCO3, water and dried over Na2SO4. The solvent was removed under vacuum to give crude (2S)-2-azido-3-(piperidin-4-yl)-N-(quinolin-3-yl) propanamide LXXVII (320 mg). ESIMS found for C17H20N6O m/z 325 (M+H).
