| titleOfInvention | Process for producing α-aryl-N-alkylnitrones |
| abstract | PROBLEM TO BE SOLVED: To provide an industrially advantageous method for producing an α-aryl-N-alkylnitrone. [Solution] (A) Formula (1) (In the formula, Ar represents an optionally substituted phenyl group, and X represents a halogen atom.) And benzyl halides represented by formula (2) (Wherein R 1 , R 2 and R 3 are the same or different and each represents a lower alkyl group. Here, any two or three of them together form a ring together with the bonding carbon atom) May be formed.) Is reacted with a primary amine represented by the formula (3) (In the formula, Ar, R 1 , R 2 and R 3 represent the same meaning as described above.) A step of obtaining an N-benzyl-secondary amine represented by the formula: (B) Formula (4) characterized by including the process which makes this N-benzyl secondary amine and hydrogen peroxide react in presence of a metal oxide. (In the formula, Ar, R 1 , R 2 and R 3 represent the same meaning as described above.) The manufacturing method of the alpha-aryl-N-alkyl nitrone shown by these. [Selection figure] None |
