| titleOfInvention | Process for producing 5- (haloacetyl) -8- (substituted oxy)-(1H) -quinolin-2-ones |
| abstract | The present invention relates to a process for producing 5- (α-haloacetyl) -8-substituted oxy- (1H) -quinolin-2-ones. The method comprises reacting (i) (a) 8-hydroxy- (1H) -quinolin-2-one with an acylating agent and a Lewis acid to give 5-acetyl-8-hydroxy- (1H) -quinoline-2. Or (b) reacting 8-hydroxy- (1H) -quinolin-2-one with an acylating agent to form 8-acetoxy- (1H) -quinolin-2-one; and In situ treating 8-acetoxy- (1H) -quinolin-2-one with Lewis acid to give 5-acetyl-8-hydroxy- (1H) -quinolin-2-one; or (c) 8- Reaction of acetoxy- (1H) -quinolin-2-one with Lewis acid to form 5-acetyl-8-hydroxy- (1H) -quinolin-2-one; (ii) prepared in step (i) 5 -Acetyl-8-hydroxy- (1H) -quinolin-2-one is represented by the formula RL ( Wherein R is a protecting group and L is a leaving group) in the presence of a base and a solvent to give 5-acetyl-8-substituted oxy- (1H) -quinoline-2- And (iii) reacting 5-acetyl-8-substituted oxy- (1H) -quinolin-2-one with a halogenating agent in the presence of a solvent to give 5- (α-haloacetyl) -8 -Forming a substituted oxy- (1H) -quinolin-2-one. |
