Ethanol → HCID 14851905, compound

Participants

Reaction Steps

The title compound was obtained by coupling 4-(2-chlorophenyl)-2-iodo-9-methyl-6H-thieno [3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepine with 2-ethynylpyridine under the conditions used 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. The fractions homogenous by TLC were combined and evaporated. Crystallization of the residue from ethyl acetate and recrystallization from tetrahydrofuran/methanol gave off-white crystals of 4-(2-chlorophenyl)-9-methyl-2-[2-(2-pyridinyl)-ethynyl]-6H-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepine with m.p. 153°-155°.
