Procedure

The general procedure of Example 35 was repeated except that 50 grams of p-nonyl phenol (0.227 mole) was used, along with 9.73 grams (0.238 mole) of 98% sodium hydroxide and 23.0 grams (0.284 mole) of the formaldehyde solution to obtain the intermediate 2-hydroxymethyl-4-nonyl phenol. The desired product, 2-(2-hydroxyethyl)thiomethyl-4-nonyl phenol, was obtained from 23.85 grams (0.095 mole) of the intermediate and 7.4 grams of the 2-mercaptoethanol (0.095 mole) in 50 ml of toluene, along with 0.10 gram of the catalyst. Structural formula 27 for the product was confirmed by 1H and 13C NMR.
