To a solution of 1-(2-chloroethyl)-3-[4-(3-cyano-1-ethyl-6-methoxy-1H-indol-2-yl)-phenyl]-urea (100 mg, 0.252 mmol) in MeOH (10 mL) is added aqueous 1M KOH (504 uL) and then stirred at 49° C. for 24 h. The solvents are removed under reduced pressure. The residue is diluted with ethyl acetate and then washed with water. The organic layer is dried over anhydrous MgSO4, filtered and concentrated under reduced pressure. The residue is diluted with ethyl acetate and then triturated with hexane and the precipitate collected by filtration and washed well with 50% ethyl acetate in hexane and dried in vacuo to afford 1-ethyl-6-methoxy-2-[4-(2-oxo-imidazolidin-1-yl)-phenyl]-1H-indole-3-carbonitrile (56 mg, 62%).
