Reaction Steps

To a solution of (S,Z)—N-(3-chloro-1-fluoro-7-((3-methylpyridin-2-yl)amino)spiro[chromeno[2,3-c]pyridine-5,4′-[1,3]oxazinan]-2′-ylidene)benzamide (0.069 g, 0.130 mmol) in THF (2 mL) was added ammonia, 2.0M solution in methanol (10 ml, 20.00 mmol) and heated in a sealed tube at 50° C. for 15 h. The reaction was concentrated and purified by HPLC to afford (S)-3-chloro-1-fluoro-N7-(3-methylpyridin-2-yl)-5′,6′-dihydrospiro[chromeno[2,3-c]pyridine-5,4′-[1,3]oxazine]-2′,7-diamine as a white solid. MS m/z=426.1 [M+H]+.
