Procedure

A solution of (R)-6-(6-chloropyridine-3-sulfonyl)-4a-ethoxymethyl-1-(4-fluorophenyl)-4,4a,5,6,7,8-hexahydro-1H-1,2,6-triazacyclopenta[b]naphthalene (0.013 g) and pyrrolidine (0.025 mL) in acetonitrile was heated at 100° C. in a microwave reactor for 10 minutes. The solution was concentrated under reduced pressure, and the residue was purified by column chromatography on silica gel, eluting with a mixture of dichloromethane and ethyl acetate (5:1 by volume), to afford the title compound as a clear gum (0.0080 g). LCMS (Method B): 538 (M+H)+, Retention time 4.0 minutes.
