2,4,5-trichloropyrimidine (0.20 g) and 7-hydroxy-2-methyl-2,3-dihydro-isoindol-1-one are dissolved in DCM (10 mL), cooled to 0° C. and combined with caesium carbonate (0.75 g). The cooling bath is removed and the mixture is stirred for 16 h. For working up the mixture is combined with 10% NaCl solution (100 mL) and extracted three times with 75 mL ethyl acetate. The combined organic phases are dried on magnesium sulphate, filtered off from the desiccant and the solvent is eliminated in vacuo.
