Participants

Reaction Steps

Methanesulfonyl chloride (0.86 ml, 1.1 mmol) was added to a stirred solution of ethyl 3-[(2-aminophenyl)sulfanyl]-6-(3-pyridylmethoxy)benzo[b]thiophene-2-carboxylate (Example 12 220 mg, 0.5 mmol) and N,N-diisopropylethylamine (0.2 ml, 1.1 mmol) in dichloromethane (3 ml). The mixture was left at ambient temperature for 20 hours and then diluted with dichloromethane and washed with water. The organics were dried (magnesium sulfate), and evaporated under reduced pressure. The residue was flash chromatographed on silica gel using diethyl ether, and then ethyl acetate, as eluant. The title product was crystallised from diethyl ether to give a colourless solid (232 mg).
