| titleOfInvention | Method of producing 2-aminobenzophenone or its 2ъ-derivatives |
| abstract | The invention relates to alpha amines, in particular the preparation of 2-adenobenzophenone or its 2-methyl- or 2-methoxy-substituted intermediates for the synthesis of chiral reagents used in the production of d-amino acids. The goal is to increase the yield of the target product and simplify the process. The latter is derived from the phenylmagnesium Bromide derivative and 2-methyl-3,1, 4-benzoxaz-4-one in the medium and ether mainly at. (-40) - (+10) C and subsequently separating the magnesium and solvent salts from 2- acetamide derivative, its hydrolysis of conc. HCl when heated, alkalinized to isolate the desired product. The starting 2-methyl-3, 1,4-benzoxaz-4-one is used in the form of a 1.5-2 M solution in CH, C1 2. The reaction products, after removing the solvent, are directly dissolved in an aqueous solution of HCl. These conditions allow the yield of the target product from 30 to 68-73% while reducing the number of operations using smaller volumes of solvent. 1 hp f-ly, 1 tab. $ W |
