Reaction Steps

To a solution of 1:5-(1-hydroxy-2-cyclohexylcarbonylamino-2-tetrahydropyran-4-ylethyl)-2-thioxo-1,3,4-oxadiazoline (prepared in step 1 of example 8; 281 mg) in N,N-dimethylformamide (2 ml) were added N-methyl-N-(1,1-dimethyl-2-chloroethyl)amine (125 mg) and potassium carbonate (328 mg) and the mixture was stirred for 3 hours at 70° C. The reaction mixture was poured into brine and was extracted with ethyl acetate, dried over anhydrous magnesium sulfate and concentrated. The residue was purified by column chromatography on silica gel (ethyl acetate:methanol=9:1) to give N′-(3,4,4-trimethyl-1,3-thiazolidin-2-ylidene)-[3-cyclohexylcarbonylamino-3-(tetrah ydropyran-4-yl)-2-hydroxypropanohydrazide] (279 mg).
