実験手順
A hot solution of 13 g (0.05 mol) of 4'-chloro-4-nitrobenzophenone in 80 ml of ethanol was added in small portions, while stirring, to a hot solution of 53.5 g (0.24 mol) of tin(II)chloride dihydrate in 50 ml of concentrated hydrochloric acid, which was accompanied by a violent reaction. After all had been added, the mixture was heated on a steam bath for two hours and was then poured into an aqueous potassium hydroxide solution, while stirring. A precipitate was formed which was suction-filtered off and dissolved in boiling ethanol. The insoluble matter was filtered off, and the filtrate was allowed to cool. The light yellow crystals which precipitated were suction-filtered off.
