To a suspension of cis-4-(6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyrazin-1-yl)cyclohexanamine hydrochloride (0.106 g, 0.206 mmol, Example #D.1.1) in DCM (4 mL) was added TEA (0.086 mL, 0.62 mmol). The reaction mixture was sonicated until the reaction was homogeneous. To the reaction solution was added perfluorophenyl 2-cyanoacetate (0.078 g, 0.31 mmol, Preparation #6). The resulting solution was stirred at ambient temperature for about 16 h. The crude reaction mixture was purified by silica gel chromatography (40 g) eluting with a gradient of 0-20% EtOAc in DCM and then further purified by RP-HPLC (Table 2, Method e) to give N-(cis-4-(6H-pyrrolo[2,3-e][1,2,4]triazolo[4,3-a]pyrazin-1-yl)cyclohexyl)-2-cyanoacetamide with 3 equiv NH4OAc as an excipient (0.025 g, 22%). LC/MS (Table 2, Method a) Rt=1.33 min; MS m/z: 324 (M+H)+.
