Procedure

To a stirred suspension of 10% palladium on carbon (50 mg) in methanol (5 mL) was added a solution of 3-(benzothiazol-2-yl)-9-(5,6,7,8-tetrahydro-[1,8]naphthyridin-2-yl)-non-2-enoic acidtert-butyl ester 29-7c (190 mg) in ethanol (5 mL) and the mixture was subjected to an atmosphere of hydrogen for 48 hours. The reaction mixture was filtered through Celite and concentrated at reduced pressure. The resulting oil was purified by flash column chromatography over silica gel with 4:1 hexanes/acetone to give 29-8c as a colorless oil.
