実験手順

The titled compound was synthesized by steps analogous to those described in method BB12 above, but using (S)-7-bromo-3-chloro-1-fluoro-5′H-spiro[chromeno[2,3-c]pyridine-5,4′-thiazol]-2′-amine (prepared as described in Method BB26 but using 7-bromo-3-chloro-1-fluoro-5H-chromeno[2,3-c]pyridin-5-one), 2-fluoropyridin-3-ylboronic acid and 2-fluoropyridin-4-ylboronic acid.
