Reaktionsschritte
1-(2-aminophenoxy)-3-[4-(3,4-dichlorophenoxy)-1-piperidinyl]-2-propanol (75 uL, 0.2M/NMP) was mixed with 3-methyl glutaric anhydride (3 eq, 225 uL 0.2M /NMP) to get a product containing both esther and amide. After evaporation of the mixture it was treated with 3 eq 0.5M LiOH in (THF/water 1:4) for two hours at 80° C. to hydrolyse the esther. The reaction mixture was diluted with more water (2 mL) and the desired product was extracted with 5×500 uL EtOAc which was evaporated to dryness.
