This method provides cleaner material in higher overall yield than that obtained using previously reported methods.Keywords: Hydrides; Hydrogenation; Synthesis (chemical); Benzoic acids; Organic acids; 2 (3 methyl 2,5 dihydropyrrol 1 yl)benzoic acid; 2 (3 methyl 2,5 dioxopyrrolidin 1 yl)benzoic acid; anthranilic acid; benzoic acid derivative; citraconic anhydride; unclassified Acids; Alkaloids; Amines; Anhydrides; Hydrogenation200310.1055/s-2003-380652015-12-09
