A mixture of [(R)-1-(4-fluorophenyl)-6-[[6-(4-morpholinyl)-3-pyridinyl]sulfonyl]-1,4,7,8-tetrahydro-1,2,6-triazacyclopenta[b]naphthalen-4a-yl]methanol (0.21 g), copper iodide (0.0080 g) and acetonitrile under argon was treated with 2-(fluorosulfonyl)difluoroacetic acid (0.062 mL), and the resulting mixture was heated at 50° C. for 30 hours. The mixture was cooled to room temperature, partitioned between water and ethyl acetate and the aqueous phase extracted with ethyl acetate. The combined organic phase was dried over sodium sulfate and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel, eluting with a mixture of cyclohexane and ethyl acetate (1:0 to 1:1 by volume), and then by preparative reverse-phase HPLC, eluting with a mixture of acetonitrile and water containing 0.1% formic acid (1:1 to 7:3 by volume) to afford the title compound as a white solid (0.021 g). LCMS (Method C): 576 (M+H)+, Retention time 11.6 minutes.
