| titleOfInvention | Method for producing 3-aminosteroid derivative |
| abstract | PROBLEM TO BE SOLVED: To provide a method for easily producing a 3-aminosteroid derivative useful as an intermediate for synthesizing a drug in a high yield. SOLUTION: (a) General formula (1) [Wherein, R 1 represents an alkyl group having 1 to 4 carbon atoms, an alkyl group having 1 to 10 carbon atoms which may have a specific substituent, and R 2 represents α-OH or β-OH Represented by the general formula (2) Is obtained by reacting with a hydrazine hydrate or phenylhydrazine to obtain a 3-phthalimide steroid derivative represented by the general formula (3): (Wherein R 1 is as defined in formula (1); 3 represents α-NH 2 or β-NH 2 ), and the resulting compound is treated with a solution of an organic acid or a mineral acid to obtain an organic acid or a mineral acid. And then converted to the free compound. |
