| titleOfInvention | Method for preparing O-chloromethyl-phenylglyoxylic acid derivative |
| abstract | a) reacting a compound of formula (II) with an organolithium compound of formula (III): b) reacting the resulting lithium complex with a compound of formula (IV) to produce a compound of formula (V); c) the obtained compound is in any order oximeized with c1) O-methylhydroxylamine or oxime with hydroxylamine and then methylated or fluoromethylated or difluoromethylated and c2) chloroformic acid. Described is a process for the preparation of the compound of formula (I) below comprising reacting with an ester.n n n n n n n n Wherein X is a radical inert to the reaction, m is 0-4, R 3 is hydrogen, CH 3 , CH 2 F or CHF 2 , and Y is OR 4 , N (R 5 ) 2 or N ( CH 3 ) OCH 3 group, R 4 and R 5 are independently of each other hydrogen or C 1 -C 8 alkyl or (R 5 ) 2 is combined with the nitrogen atom to which they are attached to provide a 5- or 6-membered or substituted And R 1 and R 2 are each independently of the other C 1 -C 6 alkyl, C 1 -C 6 alkenyl, C 1 -C 6 alkoxyalkyl or C 3 -C 6 cycloalkyl, or R 1 And R 2 is combined with a nitrogen atom to form an unsubstituted or substituted 6- or -unused ring which may further contain additional nitrogen atoms in addition to this nitrogen atom, R 7 is an organic anion radical and substituent Y 1 is the same Or different from each other, OR 4 , N (R 6 ) 2 or N (CH 3 ) OCH 3 group or imidazole or halogen, R 4 is C 1 -C 8 alkyl, R 6 is C 1 -C 8 alkyl Is (R 6) 2 is a nitrogen atom and combined to 5-membered or 6-membered unsubstituted or substituted to form a ring and the Y 1 is imidazole or halogen which they are attached, and the group may be substituted by Y. |
