Procedure

98 mg (0.65 mmol) of 5-methyl-3H-oxazolo[4,5-b]pyridin-2-one, 200 mg (0.65 mmol) of 3-(4-methylpiperazin-1-yl)propyl (3-hydroxymethylphenyl)carbamate and 325 mg (0.98 mmol) of polymer-bound triphenylphosphine (3 mmol/g) are suspended in 5 ml of DMF, and the mixture is shaken for 30 min. 229 mg (0.98 mmol) of di-tert-butyl azodicarboxylate are subsequently added. The reaction mixture is shaken at room temperature. The reaction mixture is filtered and rinsed with THF, and the filtrate is evaporated. The residue is purified by column chromatography on silica gel.
