methyl 2-(3-chloroanilino)propanoate

反応条件: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To a sealed tube containing a clear, slightly yellow solution of 3-chloroaniline (2.5 g, 19.60 mmol) and methyl 2-bromopropanoate (3.93 g, 23.52 mmol) in DMF (39.2 mL) was added potassium iodide (0.325 g, 1.960 mmol) and potassium carbonate (4.06 g, 29.4 mmol). The vessel was sealed with a Teflon screw cap possessing an o-ring. The resulting suspension was warmed to 100° C. After 5 h, the resulting dark brown reaction mixture was stopped and cooled to rt. The reaction was filtered to remove the solid, rinsing with EtOAc. The filtrate was partitioned between EtOAc and water and the layers were separated. The aqueous layer was extracted with EtOAc (2×). The combined organic layers were washed with brine, dried over sodium sulfate, filtered and concentrated to give a brown liquid weighing 6.30 g. Purification by normal phase chromatography gave the desired product (1.04 g, 25%) as a clear, yellow oil.
