Participants

Reaction Steps

A solution of 100 mg (0.26 mmol) of 2-(3-(2,6-dimethylphenylamino)-6-(phenylamino)-1H-indazol-1-yl)acetic acid 69 (Example 34) in DCM (10 mL) at room temperature was treated with Et3N (43 μL, 1.2 eq) followed with Bop-Cl (73 mg, 1.1 eq) and 1-methylpiperazine (35 μL, 1.2 eq). The mixture was stirred at room temperature for 3 hours before it was quenched with water (5 mL). The organic layer was separated and washed with water, brine, dried over sodium sulfate and filtered. The filtrate was concentrated and purified by column chromatography on silica gel (eluens: DCM:MeOH:NH4OH, 20:1:0.2) to give the title compound 70. 1H-NMR (CDCl3) δ 2.28 (s, 6H), 2.32 (s, 3H), 2.35-2.45 (m, 4H), 3.59-3.69 (m, 4H), 4.98 (s, 2H), 5.91 (s, 1H), 7.04 (t, J=7.3 Hz, 1H), 7.08-7.16 (m, 3H), 7.19 (s, 1H), 7.32 (t, J=8.4 Hz, 2H), 7.47 (s, 1H), 7.58 (d, J=7.7 Hz, 2H). Mass Spectrum (ESI) m/e=471 (M+1).
