Versuchsvorschrift
5-Chloro-2-hydroxy-benzaldehyde (3 g, 19.16 mmol),2-Iodo-propane (4.88 g, 28.74 mmol) and K2CO3 (4 g, 28.74 mmol) was mixed in anhydrous DMF. The reaction tube was placed into the cavity of a focused monomode microwave reactor and the contents of the flask were irradiated for 30 min at 100° C. Then the solution was filtered and the filtration was concentrated to obtain the crude product (3 g). The crude product was used into next step reaction without further purification.
