Benzyl chloroformate → HCID 22060503, compound

Participants

Reaction Steps

To a mixture of 5-aminobenzene-1,3-diol (0.60 g, 3.7 mmole) and sodium hydrogencarbonate (1.4 g, 16 mmole) in THF/water (15 mL, 1:1 v/v) was added dropwise benzyl chloroformate 1.6 mL, 11 mmole). After 3 h at rt, THF was removed under vacuum and the remaining aqueous layer was extracted with ethyl acetate. Purification by column chromatograpy over silica gel provided benzyl N-(3,5-dihydroxyphenyl)carbamate. 1H NMR (CD3OD): δ 7.42-7.25 (m, 5H), 6.46 (d, 2H, J=2.4 Hz), 5.97-5.94 (m, 1H), 5.14 (s, 2H).
