Participants

Reaction Steps

To a mixture of (E)-methyl 4-(4-amino-1H-indazol-1-yl)-4-(4-chlorophenyl)hex-2-enoate (120 mg) and NMM (98 mg) in DCM (5 mL) was added MsCl (45 mg). Then the mixture was stirred at room temperature for 2 h. The solution was quenched with saturated NH4Cl solution, and extracted with ethyl acetate (30 mL). The organic layer was washed with brine, dried over dry sodium sulfate, filtered and evaporated. The residue was purified by silica gel chromatography (PE/EA=5/1) to afford the title compound as a pale yellow solid. LC/MS m/z=448.2[M+H]+.
