Abstract
PURPOSE: To prepare the title compound having blood cholesterol depressing activity, economically, by reacting 4-mercapto-2,6-di-t-butylphenol with acetone in the presence of a specific sulfonic acid sulfonium salt.
CONSTITUTION: The objective compound II is prepared by reacting (A) 1 mole of 4-mercapto-2,6-di-t-butylphenol with (B) acetone in the presence of (C) 0.001W 2 moles of a sulfonic acid sulfonium salt of formula I (R1, R2 are alkyl, arylalkyl, or R1 and R2 may together from tetramethylene or pentamethylene; R3 is arylalkyl; R4 is alkyl, aryl, arylalkyl), e.g. S-benzyl-S,S-dimethylsulfonium p-toluenesulfonate, etc.
