Reaction Steps

To a solution of (S)-N-{2-[5-[2-(7-azabicyclo[2.2.1]hept-7-yl)-1,1-dimethyl 2-oxo-ethyl]-2-(3,5-dimethylphenyl)-1H-indol-3-yl]-propyl}-2,4-dinitrobenzenesulfonamide (52.5 mg in 1.6 mL dry benzene) was added 20.3 mg 2-morpholin-4-yl-ethanol followed by 40.8 mg triphenylphosphine and 0.025 mL of diethyl azodicarboxylate added dropwise. After 20 minutes, the mixture was concentrated and the crude reaction product purified by flash chromatography on silica gel (ethyl acetate:hexane, 1:3) to give the title compound (95.2 mg).
