1,1'-Carbonyldiimidazole → HCID 86680397, compound

Participants

Reaction Steps

To a solution of ethyl 2-(4-amino-3-(hydroxymethyl)phenoxy)acetate (0.2 g, 0.888 mmol) in THF (5 mL) was added CDI (0.216 g, 1.332 mmol) at 0° C. and stirred at RT for 2 h. The reaction mixture was diluted with water and extracted with ethyl acetate. The organic layer washed with brine, dried over sodium sulfate and concentrated. The crude product was purified by flash chromatography on silica gel using hexane/ethyl acetate as eluent to yield ethyl 2-((2-oxo-2,4-dihydro-1H-benzo[d][1,3]oxazin-6-yl)oxy)acetate (0.03 g, 13%). 1H NMR: 400 MHZ, DMSO-d6: δ 1.22 (t, J=7.20 Hz, 3H), 4.17 (q, J=6.80 Hz, 2H), 4.72 (s, 2H), 5.23 (s, 2H), 6.79-6.86 (m, 3H), 10.01 (s, 1H).
