Procedure
A mixture of ethyl 1-[(2S,3R)-2-hydroxy-5-(2,3-dichlorophenyl)-3-pentyl]-1,2,4-triazole-3-carboxylate (11.6 mg) and ammonium hydroxide (28% in water; 0.5 ml) in tetrahydrofuran (3 ml) was heated in a steel sealed tube at 120° C. overnight. The mixture was taken up in dichloromethane, washed with water, dried, and evaporated. The residue was purified by column chromatography on silica gel, eluting with a mixture of dichloromethane and methanol (20:1) to give a white powder of 1-[(2S,3R)-2-hydroxy-5-(2,3-dichlorophenyl)-3-pentyl]-1,2,4-triazole-3-carboxamide (4.2 mg).
