| titleOfInvention | Preparation method of oxaziclomefone |
| abstract | The invention relates to the field of oxaziclomefone preparation, and discloses a method for preparing oxaziclomefone, which comprises the following steps: reacting a compound represented by formula (1) or formula (2) with 1-methyl-1- (3, 5-dichlorophenyl) ethylamine represented by formula (3) in the presence of paraformaldehyde and a catalyst. Wherein R is C 1 ‑C 5 Alkyl groups of (a); the general formula of the paraformaldehyde is- (CH) 2 O) n N is an integer from 2 to 100; the catalyst contains alcohol, alkali and free radical polymerization inhibitor. By adopting the method, the synthetic route of the oxaziclomefone is shortened, the raw material stability is good, and the yield of the oxaziclomefone is high. |
