Procedure

To a solution of (E)-1-(1-(quinolin-6-ylmethyl)-1H-[1,2,3]triazolo[4,5-b]pyrazin-6-yl)ethanone O-2-aminoethyl oxime (example 34) (6 mg, 0.017 mmol) in DCM (5 mL) were added methyl chloroformate (2.66 mg, 0.028 mmol) and triethyl amine (3.35 mg, 0.033 mmol). The mixture was stirred at rt for 10 h. After concentration, the crude was purified by chromatography on silica gel to afford 3.4 mg (46%) of the title compound. 1H-NMR (400 MHz, CDCl3) δ ppm 9.41 (s, 1H), 8.93 (s, 1H), 8.14 (dd, 2H), 7.92 (s, 1H), 7.84 (dd, 1H), 7.44 (m, 1H), 6.12 (s, 2H), 4.42 (t, 2H), 3.69 (s, 3H), 3.60 (m, 2H), 2.39 (s, 3H). LCMS (method B): [MH]+=421, tR=1.95 min.
