Reaction Steps
The benzaldehyde used in Example 4 was prepared in a similar manner to that described for Example 3. From 7.40 g (32.4 mmol) of 2-methylsulfonyl-4-(1,1-dimethylethyl)phenol (see German Offenlegungsschrift DE 32 08 190 Al to Englert et al, assigned to Hoechst AG as an example of how to obtain this material) there was obtained 4.41 g (17.2 mmol, 53%) of 2-hydroxy-3-methylsulfonyl-5-(1,1-dimethylethyl)benzaldehyde; mp 133°-135° C.
