Synthesis of intermediate for the manufacture of 5,6-dihydro-2-methyl-N-phenyl-1,4-oxathiin-3-carboxamide.

摘要

2 - [(2-hydroxyethyl)thio] - 3 - oxo - N - phenylbutanamide, which is an intermediate useful in the manufacture of the fungicide, 5,6-dihydro-2-methyl-N-phenyl-1,4-oxathiin-3-carboxamide, is made by reaction of d-(2-hydroxyethyl) disulfide with acetoacetanilide in its ionized form. The intermediate may be cyclized to from the fungicide.
