Ethanol → HCID 14851906, compound

Participants

Reaction Steps

The title compound was obtained by reacting 4-(2-chlorophenyl)-2-iodo-9-methyl-6H-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepine with phenylacetylene under the conditions described in EXAMPLE 37. The product was isolated by chromatography over the 50-fold amount of silica gel using 5% (v/v) of ethanol in methylene chloride for elution. The combined clean fractions were evaporated and the residue was crystallized from ethyl acetate to give colorless crystals of 4-(2-chlorophenyl)-9-methyl-2-(phenylethynyl)-6H-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]-diazepine with m.p. 215°-217°.
