Diisopropylethylamine → 1-(6-(5-fluoroindoline-1-carbonyl)pyrimidin-4-yl)spiro[piperidine-4,4'-pyrido[2,3-d][1,3]oxazin]-2'(1'H)-one

Participants

Reaction Steps

0.10 g (0.36 mmol) (6-chloro-pyrimidin-4-yl)-(5-fluoro-2,3-dihydro-indol-1-yl)-methanone were added to 92 mg (0.36 mmol) spiro[piperidine-4,4′-pyrido[2,3-d][1,3]oxazin]-2′(1′H)-one-hydrochloride and 146 μL (0.84 mmol) DIPEA in 1.8 mL DMF. The reaction mixture was stirred overnight at RT. Then the reaction mixture was purified by preparative HPLC-MS. The product fractions were combined and lyophilised.
