Dimethylformamide → HCID 19349406, compound

Participants

Reaction Steps

A mixture of the product from Example 28 (0.6 g), S-methylthiouronium sulphate (0.56 g), 10N aqueous sodium hydroxide (1 ml) and dimethylformamide (5 ml) was stirred at room temperature for 18 h, diluted with water (20 ml) and extracted twice with dichloromethane. The extracts were combined, dried and evaporated to dryness under reduced pressure, and the residue was purified by flash column chromatography, eluting with methanol:ethyl acetate (1:49 by volume) to give 2-methyl-2-[3-methylthiomethyl-5-(1H-1,2,4-triazol-1-ylmethyl)phenyl]-propiononitrile. Nmr in deuteriochloroform: δ 8.12(1H,s), 8.0(1H,s), 7.4(1H,m), 7.27(1H,m), 7.15(1H,m), 5.38(2H,s), 3.66(2H,s), 2.0(3H,s), 1.72(6H,s).
