Reaction Steps

6-(1H-Indol-4-yl)-1-(phenylsulfonyl)-4-(1H-tetrazol-5-yl)-1H-indazole (1.41 g, 3.19 mmol) was slurried into anhydrous chloroform (20 ml), treated with chloroacetyl chloride (1.023 ml, 12.78 mmol) and heated at 100° C. in a Biotage Initiator microwave for 30 mins, the mixture was split into 4 batches for the microwave reaction. The mixtures were allowed to cool to room temperature and the resultant precipitate collected by filtration to give the title compound as a yellow/brown solid (0.237 g). LCMS (Method A): Rt 1.25 mins, MH+490.
