Procedure
6-(3-Pyridin-4-yl-propoxy)-2-thieno[3,2-c]pyridin-6-yl-chromen-4-one oxime, hydrochloride was prepared in 7% overall yield using the method described in example 127, starting from 6-hydroxy-2-thieno[3,2-c]pyridin-6-yl-chromen-4-one O-tert-butyl oxime (example 127A) and 4-(3-Chloro-propyl)-pyridine hydrochloride, prepared from 4-pyridine propanol (U.S. Pat. No. 6,362,336).
