Procedure
One mole of glutaric anhydride and one mole of N-hydroxysuccinimide were treated in dichloromethane with 1.2 equivalents of triethylamine. This reaction was stirred for 40 minutes, acidified by the addition of 0.5 N hydrochloric acid (HCl) (aqueous), and then extracted with ethyl acetate to form mono N-hydroxysuccinimide glutarate. This glutarate was then combined with 5 moles of thionyl chloride and stirred at room temperature for three hours. The resulting reaction mixture was dried to remove volatiles, and thereby form N-hydroxysuccinimidyl glutaryl chloride.
