Reaction Steps

Diethylcarbamoyl chloride (1.2 ml; 9.4 mmol) was added to cyclohexylmethyl 1,2,4-triazol-3-yl sulfone (2.0 g; 8.7 mmol) in dry pyridine (10 ml) under dry nitrogen, and the solution stirred at room temperature overnight. The resulting mixture was poured into 2M hydrochloric acid (40 ml) at 2° C. and the cloudy solution extracted into ethyl acetate (3×60 ml). The extracts were combined, dried (Na2SO4), filtered and evaporated, to afford a colorless oil which was dissolved in 95% dichloromethane, 5% acetonitrile, and the solution filtered through silica. Evaporation afforded 3-(cyclohexylmethylsulfonyl)-N,N-diethyl-1,2,4-triazole-1-carboxamide (2.82 g; 98%) as white crystals, m.p. 40°-46° C. (Found, C: 51.04; H: 7.39; N: 17.01; S: 9.81.
