Versuchsvorschrift
The title compound was prepared by the method of Example 3 using 557 mg of the title product of Example 72 instead of the title product of Example 2. The reaction mixture was passed three times through a column of potassium carbonate powder and concentrated in vacuo to dryness. Crystallization for acetonitrile gave 257 mg of the title compound. Anal. Calc'd. for C18H19N3O4S: C, 57.90; H, 5.13; N, 11.25; S, 8.59. Found: C, 57.63; H, 5.15; N, 11.32; S, 8.65.
