Allyl bromide → HCID 86683452, compound

Participants

Reaction Steps

0.5 ml (5.71 mmol) of allyl bromide and 0.19 g (4.28 mmol) of sodium hydride at 60% are added, under an inert atmosphere at ambient temperature, to 1 g (2.85 mmol) of 6-[(1-methoxy-2-methylindolizin-3-yl)carbonyl]-2H-3,1-benzoxazine-2,4(1H)-dione in 15 ml of DMF. The reaction medium is stirred for 2 hours at ambient temperature and then concentrated under reduced pressure. After the addition of ice to the residue, the precipitate formed is filtered off, rinsed with water, and dried under reduced pressure at 50° C. overnight. 0.773 g of a yellow solid is obtained.
