Participants

Reaction Steps

To a solution of (S,E)-1-(1-((7-fluoroquinolin-6-yl)methyl)-1H-[1,2,3]triazolo[4,5-b]pyrazin-6-yl)ethanone O-pyrrolidin-3-yl oxime (example 19) (20.0 mg, 0.05 mmol) in EtOH (5 mL) was added isocyanatotrimethylsilane (7.9 mg, 0.07 mmol). The mixture was stirred overnight. The solvent was removed under reduced pressure. The residue was diluted with MeOH (3 mL) and filtered. The filtrate was purified on HPLC (basic with 0.05% NH4OH) to give the title compound as a white solid (15.0 mg, 64%). 1H-NMR (400 MHz, DMSO-d6) δ ppm 9.31 (s, 1H), 8.92 (dd, 1H), 8.40 (d, 1H), 8.17 (d, 1H), 7.82 (d, 1H), 7.53 (dd, 1H), 6.23 (s, 2H), 5.77 (s, 2H), 4.99 (m, 1H), 3.59 (d, 1H), 3.51-3.47 (m, 1H), 3.44-3.38 (m, 1H), 3.28-3.23 (m, 1H), 2.26 (s, 3H), 2.18-2.17 (m, 2H). LCMS (method A): [MH]+=450, tR=4.38 min.
