YieldReaction ConditionsOperation in experiment
51% In a glass RBF equipped with a Teflon-coated magnetic stirrer was dissolved (2-chloro-ethoxy)- acetic acid (1 eq.) in dichlormethane (0.67 M). To this was then added sequentially pyridine (2.5 eq.) and thionyl chloride (1.5 eq.), the latter of which was added drop-wise over 10 mm. The resulting orange solution was stirred at RT under nitrogen for 30 mm before 2-bromo-4-fluoro-5- nitro-phenylamine (1 eq.) was added drop-wise as a solution in dichloromethane (0.67 M). Finally, triethylamine (3.5 eq.) and DMAP (0.1 eq.) were added and the resulting mixture was allowed to stir at RT for 18 h. The reaction was quenched with the addition of water and extracted with EtOAc. The combined organic extracts were then washed further with water and brine, dried over MgS 04, filtered and the filtrate concentrated in vacuo. Further purification by way of column chromatography (Si02, gradient elution, 9:1 (v/v) Hex: EtOAc - EtOAc) furnish the desired product as an orange oil that solidified upon standing (51percent yield).
