Versuchsvorschrift
5 ml of anhydrous dichloromethane and 0.1 ml of anhydrous DMF are added to 2.26 mmol of Compound 1. The mixture is cooled to 0° C. and 2.7 mmol of oxalyl chloride are added. The mixture is stirred at 20° C. and then added at 0° C. to a mixture of 2.26 mmol of diethylamine, 5 ml of anhydrous dichloromethane and 6.8 mmol of diisopropylethylamine. The reaction medium is stirred for 3 hours at 20° C. When the reaction is complete, the medium is diluted in 50 ml of dichloromethane and then washed with 2×30 ml of water and 1×50 ml of saturated NH4Cl solution, dried over Na2SO4 and evaporated to dryness on a rotavapor. After flash chromatography (eluent: heptane/EtOAc), Compound 18 is isolated in the form of a yellow oil (48% yield).
