Versuchsvorschrift

A mixture of 8 gm (0.0464 mol) of 2,6-diphenyl-4H-thiopyran-4-one-1,1-dioxide of Example 1, 3.1 gm (0.047 mol) of malononitrile, 50 ml of alcohol and 20 drops of piperidine was refluxed for 1 hour. The reaction mixture was cooled to room temperature and the title compound was collected and recrystallized from 100 ml of toluene (mp 216°-217° C.).
