2-Amino-N-isopropylacetamide → HCID 59511750, compound

Participants

Reaction Steps

To a solution of 2-amino-N-isopropylacetamide (INTERMEDIATE I.1) (4.77 g, 41.1 mmol) in acetonitrile (50 mL) was added 6-hydroxy-1H-benzo[d][1,3]oxazine-2,4-dione (6.13 g, 34.2 mmol). The mixture was stirred for 16 h at room temperature during which time a very thick precipitate formed. The mixture was diluted with dichloromethane (100 mL) and the solid collected by filtration and washed with dichloromethane (2×20 mL) to afford 2-amino-5-hydroxy-N-(isopropylcarbamoylmethyl)benzamide (INTERMEDIATE II.1) (6.75 g, 32.0 mmol, 78%).
