Reaction Steps

To a solution of methyl 3-(4-(tert-butoxycarbonylamino)phenyl)-[1,2,4]triazolo[4,3-a]pyrazine-8-carboxylate (61D) (130 mg, 0.35 mmol) in CH2Cl2 (1 mL) was added TFA (1 L). The resulting mixture was stirred at room temperature for 2 h, and then concentrated in vacuo. The obtained residue was stripped with CH2Cl2 and dried in high vacuum to yield the title compound as brown oil (94 mg). HPLC/MS (Method D): retention time=0.39 min, [M+H]+=270.5.
