Procedure

The reaction of Example 13(D) is repeated except that the starting materials are methyl 5-hydroxy-2-methyl-3-indenylacetate and 2,4,6-trimethoxybenzaldehyde. With the same reaction conditions and techniques, 5-hydroxy-2-methyl-1-(2,4,6-trimethoxybenzylidene)-3-indenyl acetic acid is obtained. (R and R1 =H, R2 =OH, R3 and R4 =H, R5, R6 and R7 =OCH3, R8 =CH3, R9 =H, R10 and R11 =double bond, m=0, n=0, M=OH)
