Reaction Steps

90 mg (0.35 mmol) spiro[piperidin-4,4′-pyrido[2,3-d][1,3]oxazin]-2′(1′H)-one hydrochloride, 90 mg (0.31 mmol) 6-(6-chloro-2-methylpyrimidin-4-yloxy)-4-methylbenzo[d]oxazol-2(3H)-one and 200 μL (1.16 mmol) DIPEA in 1.5 mL DMF were stirred overnight at RT. Another 90 mg (0.35 mmol) spiro[piperidin-4,4′-pyrido[2,3-d][1,3]oxazin]-2′(1′H)-one hydrochloride and 200 μL (1.16 mmol) DIPEA were added and the mixture was stirred for 8 h at 60° C. The reaction mixture was mixed with water and stirred overnight. Then DCM was added and the mixture was stirred for a further 30 min. DCM was removed and the aqueous phase was suction filtered. The precipitate was washed with EtOH and dried.
