Procedure
This was prepared by reacting 11.4g of 2'-hydroxy-5'-methoxy-2-(methylsulfinyl)acetophenone with 7.85 g of p-cyanocinnamaldehyde in analogous fashion to 4-[2-(8-methoxy-4-oxo-4H-1-benzopyran-2-yl) ethenyl]benzonitrile. The material was recrystallized from toluene. mp 224°-26°; yield 6.5g (43%); λ max mμ (ε) 224 (20,600), 294 (21,900), 332 (43,500); ν max 820 (m), 980 (ms), 1080 (m), 1290 (m), 1580 (m), 1620 (s), 1645 (s), 2240 (m) cm-1.
