Product 1

HCID 53464322(S)-1-fluoro-7-(2-fluoropyridin-3-yl)-3-(2-methylpyridin-4-yl)-5'H-spiro[chromeno[2,3-c]pyridine-5,4'-thiazol]-2'-amine

Procedure

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-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine
