Acryloyl chloride → (S)-N-(1-(6-(5-bromo-1-methyl-2-oxo-1,2-dihydropyridin-3-ylamino)pyridin-2-yloxy)propan-2-yl)acrylamide

Participants

Reaction Steps

To an ice-cooled mixture of 107c (390 mg, 1.0 mmol) and TEA (0.53 ml, 3.0 mmol) in DCM (20 mL) was added acryloyl chloride (0.23 ml, 2.0 mmol) dropwise. The reaction mixture was stirred at rt for 2 h and quenched with water. The organic layer was separated, dried over Na2SO4, filtered and concentrated. The residue was purified by silica gel chromatography (DCM/MeOH=10/1) to give 107d (284 mg, 70%) as brown solid. MS-ESI: [M+H]+ 409.0
