実験手順
6-Nitrophthalide (14.0 g; J A Houbion, J A Miles and J A Paton, Organic Preparations and Procedures International, 11 (1), 27, 1979) in solution in acetic acid was hydrogenated over a palladium on carbon catalyst to give 6-aminophthalide (12.0 g; W R Vaughan and S L Baird, J. Amer. Chem. Soc. 68, 1314, 1946). 6-Aminophthalide (10.0 g) was converted, via the diazonium salt intermediate, to 6-chlorophthalide (8.5 g; J Tirouflet, Bull. soc. sci. Bretagne Spec. No 26, 7, 1951).
