To solution of 6-(1H-indol-4-yl)-1-(phenylsulfonyl)-1H-indazol-4-amine (1.5 g) in chloroform (20 ml) at 0° C. was added DIPEA (1.35 ml). 2-(Chloromethyl)-1,3-thiazole-4-carbonyl chloride (1.8 g) in chloroform (20 ml) was added dropwise and the mixture was stirred at 0° C. for 1 h 15 min. The mixture was allowed to warm to RT and stirring continued for 18 h. A further portion of 2-(chloromethyl)-1,3-thiazole-4-carbonyl chloride (0.2 g) was added to the mixture which was stirred at RT for 30 min. Water (50 ml) was added and the mixture was extracted with DCM (2×100 ml), separating the layers using a hydrophobic frit. The organics were collected and solvent removed in vacuo to give a brown solid which was triturated with ether (10 ml). The solid was filtered and dried in a vacuum oven overnight to afford the title compound, 1.6 g.
