Acetic Acid → HCID 66749267, compound

Participants

Reaction Steps

To a solution of Ethyl isocyanoacetate (1.00 mL, 9.15 mmol) in Tetrahydrofuran (43 mL) at −78° C. was added 2.5 M n-Butyllithium (9.15 mmol, 9.15 mmol) in hexanes under argon. The mixture was stirred for 20 min. 4-Chlorophenylacetyl chloride (0.753 g, 3.98 mmol) in Tetrahydrofuran (11 mL, 130 mmol) was added at the same temperature. After 1 h, the temperature was raised to rt and then quenched by acetic acid (0.38 g, 6.3 mmol). The mixture was washed with saturated sodium bicarbonate and brine. The organic layer was collected and dried over sodium sulfate. After evaporation, the mixture was purified by chromatography to afford ethyl 5-(4-chlorobenzyl)-1,3-oxazole-4-carboxylate (0.83 g, 78%). LCMS: (FA) ES+ 266.3.
