Participants

Reaction Steps

To a solution of 8-methoxy-9-[4-(piperazin-1-yl)phenyl]thieno[2,3-c]quinolin-4(5H)-one (89 mg, 0.23 mmol) in methylene chloride (2 mL) was added N,N-diisopropylethylamine (0.42 mL, 0.68 mmol) and methanesulfonyl chloride (45 μL, 0.27 mmol) and the reaction mixture was stirred for 1 h. The reaction mixture was quenched with water and the layers were separated. The aqueous layer was extracted with ethyl acetate and the combined organic layers were dried over Na2SO4, filtered, concentrated and the residue was purified by preparatory HPLC (C18 silica, acetonitrile/water w/0.05% TFA gradient) to afford the desired product (72 mg, 68%) as a brown solid: ESI MS m/z 470 [C23H23N3O4S2+H]+.
