Participants

Reaction Steps

To a cooled solution (ice/methanol bath) of [3-(1-cyclohexylmethyl-7-methoxy-1H-indol-3-yl)-[1,2,4]thiadiazol-5-yl]-methanol (2.3 g, 6.4 mmol) in dichloromethane (150 ml) was added methanesulfonyl chloride (0.595 ml, 7.68 mmol) and triethylamine (1.16 ml, 8.32 mmol) sequentially. The reaction was allowed to stir for 10 min and then poured into a separating funnel. The organics were washed with 5% aqueous sodium carbonate solution (2×100 ml), brine (100 ml), dried over magnesium sulfate and the solvent removed in vacuo to afford methanesulfonic acid 3-(1-cyclohexylmethyl-7-methoxy-1H-indol-3-yl)-[1,2,4]thiadiazol-5-ylmethyl ester (2.9 g, 6.7 mmol) which was used without further purification.
