Title:
METHOD FOR PRODUCING 4-(TRIFLUOROMETHYLSULFONYL)PHENOL COMPOUND
Document Type and Number:
WIPO Patent Application WO/2017/014214
Kind Code:
A1
Abstract:
A compound represented by formula (4) can be produced by adding a heterogeneous transition metal catalyst to a solution containing a compound represented by formula (3) and then subjecting the resultant mixture to a reduction reaction, wherein the compound represented by formula (3) is produced by adding a nitrogenating agent to a solution containing a compound represented by formula (2), then adding water to the resultant mixture and then fractionating the resultant solution, and the compound represented by formula (2) is produced by oxidizing a compound represented by formula (1) with hydrogen peroxide in the presence of sodium tungstate and a saturated C8 carboxylic acid, then adding water to the resultant product and then fractionating the resultant solution.
