2,2-diphenyl-1-piperazin-1-ylethanone

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Following the same procedures as in Example 1-(a) and (b), reaction and treatment were carried out using 2-trifluoromethyl-4-methyl-5-hydroxyquinoline prepared in Example 54 and N-(α,α-diphenylacetyl)piperazine in order to obtain the desired compound.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 71 g of the above-mentioned 5-(2,3-epoxypropoxy) quinoline and 94 g of N-(2,2-diphenylacetyl)piperazine were dissolved in 1.5 l of ethanol and then the resulting solution was refluxed with heating for 3 hours. After the reaction, ethanol was evaporated and the residue was purified by chromatography. The elution was carried out with a solvent miture of chloroform:methanol=50:1 (volume ratio) and the targeted fraction was concentrated under reduced pressure to obtain 101 g of 5-[3-{4-(2,2diphenylacetyl)piperazin-1-yl}-2- hydroxypropoxy]quinoline (compound No. 1). the resulting solution was refluxed with heating for 3 hours was evaporated the residue was purified by chromatography The elution methanol=50:1 (volume ratio) and the targeted fraction was concentrated under reduced pressure

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: An epoxy compound was prepared from 2-methylthio-5-hydroxyquinoline in accordance with the same procedure as in Example 1-(a), and reaction and treatment were then carried out using this epoxy compound and N-(α,α-diphenylacetyl)piperazine to obtain the desired compound. reaction and treatment
