Product 1

HCID 569627712-(4-bromophenyl)-5-cyclopropyl-6-{[2-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)ethyl](methylsulfonyl)amino}-N-methyl-2H-indazole-3-carboxamideYield 7.7%

Procedure

Intermediate (6) was prepared by alkylation of Compound (1) (210 mg, 0.45 mmol) with N-(2-bromoethyl)phthalimide (230 mg, 0.90 mmol) according to the procedure in Method C, Step a. The crude material was purified by flash column chromatography eluting with EtOAc/hexane (5-80%) to afford 2-(4-bromophenyl)-5-cyclopropyl-6-{[2-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)ethyl](methylsulfonyl)amino}-N-methyl-2H-indazole-3-carboxamide (6) as an off-white solid (22 mg).
