N-bromobutanimide → HCID 22049892, compound

Participants

Reaction Steps

Methyl 3-[4-[(2,4-difluorobenzyl)oxy]-6-methyl-2-oxopyridin-1(2H)-yl]-4-methylbenzoate (as prepared above) (1.8 g, 4.51 mmol) was taken up in CH2Cl2 (10 ml). N-bromosuccinimide (0.80 g, 4.51 mmol) was added and the mixture stirred at room temperature for two hours. The CH2Cl2 is removed in vacuo and the residue is taken up in CH3CN. The resulting precipitate is collected on a filter pad and washed with CH3CN to yield a white solid (0.30 g, 14%, first crop)
