| abstract | (57) [Summary] [Purpose] Formula I A method for producing aminochroman is provided. Aminochroman is an important intermediate for the manufacture of hypolipidemic drugs. 【Constitution】 Of nitrochromanone using zirconium oxide / isopropanol to give the corresponding aminochromene And the corresponding nitrochromene Is obtained and then this mixture is hydrogenated with hydrogen in the presence of a hydrogenation catalyst to form a compound of formula I. (Formula I To IV, R represents a lower alkyl group. ) |
