Participants

Reaction Steps

N-{5-[4-Amino-1-(phenylsulfonyl)-1H-indazol-6-yl]-3-pyridinyl}methanesulfonamide (50 mg) was dissolved in DCM (1 ml) and pyridine (0.014 ml) was added. A solution of 2-methyl-1,3-thiazole-4-carbonyl chloride (22 mg) in DCM (1 ml) was added to the reaction and the mixture was stirred at RT for 30 min. Further 2-methyl-1,3-thiazole-4-carbonyl chloride (10 mg) was added to the reaction and stirring continued for 30 min. Further 2-methyl-1,3-thiazole-4-carbonyl chloride (40 mg) was added then the reaction was quenched with water and passed through a hydrophobic frit. The organic layer was evaporated to dryness and the residue was dissolved in DMSO:MeOH (1 ml, 1:1, v/v) and purified by MDAP (method E). The compound was dissolved in MeOH containing a few drops of 2M NaOH and stirred for 5 mins at RT. The residue was dissolved in MeOH and loaded onto an SAX SPE cartridge pre-conditioned with MeOH. After eluting with MeOH and evaporating to dryness, the residue was dissolved in DMSO and purified by MDAP (method E) to give the title compound (9 mg).
