实验步骤: To a solution of 5 g 4-Chloro-phenylamine and 1.5 ml pyridine in 30 ml toluene, 8 g bromo-acetyl bromide dissolved in 10 ml toluene was added dropwise under ice cooling. After 2 h the precipitate was isolated by filtration and recrystallized from toluene to yield a white solid. was added dropwise under ice cooling After 2 h the precipitate was isolated by filtration recrystallized from toluene to yield a white solid

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: The title compound was prepared analogously to example 1 with the difference that 2-Bromo-N-(4-chloro-phenyl)-acetamide and 4-Cyano-2H-pyrazole-3-carboxylic acid ethyl ester were used instead of 2-Bromo-N-(5-chloro-pyridin-2-yl)-acetamide and 5-Thiophen-2-yl-2H-pyrazole-3-carboxylic acid ethyl ester in the alkylation step. MS (ESI+): m/e=429, chloro pattern.

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
