Sodium Hydroxide → HCID 53706495, compound

Participants

Reaction Steps

The procedure of Example 1 is followed using 6-t-butyl-3-(2-ethylhexylaminomethyl)-2,4-dimethylphenol (13.40 grams; 0.042 mole) and 1,3-benzenedisulfonyl chloride (5.5 grams; 0.02 mole) in a mixture of acetone (100 mls) and water (35 mls) while adding a solution of sodium hydroxide (1.76 grams; 0.044 mole) in water (15 mls) and maintaining the temperature at 30°-35° C. The mixture is allowed to stand at ambient temperature for 15 hours. After separating the oily layer, treating the same with ice water to effect crystallization, the solid is filtered to obtain the crude product (15.5 grams; 92% of theoretical). Recrystallization of the crude product from a mixture of benzene and cyclohexane (1 volume: 2 volumes, respectively) affords the desired product (5.5 grams; m.p. 135°-136° C.).
