Reaction Steps
2-Aminoethanol (2.9 g, 47 mmol) in 5 mL of water was added in one portion to a solution of crude 2-chloro-3,5-dinitrobenzoic acid chloride [prepared from 2-chloro-3,5-dinitrobenzoic acid 11 (5.0 g, 18.3 mmol) with SOCl2] in Me2CO (50 mL) while cooling in an ice-bath. The mixture was stirred for 30 min, then acidified with 1N HCl to pH4-5 and concentrated under reduced pressure to remove the Me2CO. EtOAc (100 mL) was added, and after 2 h a white solid was collected, washed with EtOAc and air-dried to give 2-chloro-3,5-dinitro-N-(2-hydroxyethyl)benzamide (12b) (3.0 g, 36%):
