Reaction Steps

A mixture of 2-[4-(1,4-dioxa-7-aza-spiro[4.4]non-7-yl)-3-fluorophenyl]-6-hydroxy-3,4-dihydro-2H-isoquinolin-1-one (6.9 g), (S)-2-methanesulfonylmethyl-tetrahydrofuran (3.9 g) and cesium carbonate (17.6 g) in DMF (81.6 mL) was heated overnight at 75° C. Then the reaction mixture was diluted with ethyl acetate and water. The organic phase was washed several times with water, dried over sodium sulfate and the solvent was removed in vacuum. In this way the product was obtained with molecular weight 468.53 (C26H29FN2O5); MS (ESI): 469 (M+H+).
