Procedure

A suspension of the compound of example 99 (15 g, 96.7 mmoles) in an ammonium sulfide solution (20% in water, 200 ml) was stirred overnight at 50° C. The reaction mixture was cooled down in the refrigerator and the precipitate was filtered off, providing the title compound as a yellow powder (11.33 g, yield: 83%). The spectral data are identical with literature data (Landauer et al. cited supra).
