Procedure
This was prepared by reacting 6.36 g of 2'-hydroxy-5'-methyl-2-(methylsulfinyl)acetophenone with 6.36 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 249°-51°; yield 3.5g (41%) λ max mμ (ε) 219 (19,300); 278 (13,500), 339 (41,000); ν max 825 (m), 980 (m), 1235 (m), 1580 (m), 1630 (m), 1670 (s), 2240 (m) cm-1.
