実験手順
The Grignard reagent prepared from 0.62 g. of magnesium turnings and 3.5 g. of 4-chloro-N-methylpiperidine in tetrahydrofuran is treated with a solution of 3-fluoro-9-thioxanthone (3.0 g.) in 50 ml. of tetrahydrofuran. The mixture is refluxed for four hours, cooled, treated with saturated ammonium chloride solution and extracted with ether. The ether extract is washed with water, dried and concentrated to give 3-fluoro-9-(1-methyl-4-piperidyl)-thioxanthene-9-ol, m.p. 120°-130° C.
