Procedure

Obtained by starting from (S)-ethyl 5′-(tert-butyldimethylsilyloxy)-4′-iodo-2′-(tetrahydro-2H-pyran-4-yl)-6′,8′-dihydro-5′H-spiro[cyclobutane-1,7′-quinoline]-3′-carboxylate and 2-(3,6-dihydro-2H-pyran-4-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane. A 2 M solution of caesium carbonate in water is used instead caesium fluoride. The reaction is run in tetrahydrofurane/toluene 4:1.
