Abstract: Title compds. [I; R,R1 = lower alkoxy, R2 = difluoromethyl, fluoro, chloro, X-R4 (X = O, S; R4 = C1-3 haloalkyl); R3 = H, fluoro: A = halogen, alkoxy; Hal = halogen; B = Na, K , useful as active component of herbicide, were prepd. by reaction of pyridazone derivs.(II) and alcoholate(III) in the presence of org. liquid. Thus, 30 wt% sodium methylate soln. 7.2 parts was condensed under the vacuum, made in slurry with toluene 250 parts, 1-(3-trifluoromethylthiophenyl)-4-methoxy-5-chloropyridazone-6 was added, refluxed 2 hr, filtered, recrystallized to give 1-(3-trifluoromethylthiophenyl)-4,5-dimethoxypyridazone-6 5.9 parts.

Abstract: The present invention relates to a simplified process, which avoids organo-lithium intermediates, for the preparation of erythro- alpha -piperid-2-yl-2,8-bis-(trifluoromethyl)-quinolin-4-yl-methanol, wherein 2,8-bis-(trifluoromethyl)-quinoline-4-carboxylic acid or a salt thereof is reacted with a pyrid-2-yl-magnesium halide to give pyrid-2-yl-2,8-bis-(trifluoromethyl)-quinolin-4-yl ketone in the manner of a Grignard reaction, and this product is hydrogenated, in a conventional manner, to give erythro- alpha -piperid-2-yl-2,8-bis-(trifluoromethyl)-quinolin-4-yl-methanol.
