Reaction Steps

A stirred mixture of 6-bromo-1-[(4-methylphenyl)sulfonyl]-4-(1H-tetrazol-5-yl)-1H-indazole (0.237 g, 0.565 mmol) and chloroacetyl chloride (0.136 ml, 1.696 mmol) in toluene (3 ml) was heated at 130° C. in the microwave (biotage initiator) for 20 mins. The solvent was removed in vacuo and triturated with ether (10 ml) to give the title compound as a colourless solid (0.18 g).
