Treatment of 4-aryl-2,6-dihydroxy-2,6-bis(trifluoromethyl)-3,5-piperidinedicarboxylic acid esters with phosphorus oxychloride in pyridine afforded 4-aryl-1,4-dihydro-2,6-bis(trifluoromethyl)-3,5-pyridine dicarboxylic acid esters which were reported originally by Balicki and Nantka-Namirski, but were later proven to be 4-aryl-2,6-dihydroxy-2,6-bis(trifluoromethyl)-3,5-piperidine dicarboxylic acid esters
在吡啶中用三氯氧磷处理4-芳基-2,6-二羟基-2,6-双(三氟甲基)-3,5-哌啶二羧酸酯,得到4-芳基-1,4-二氢-2,6-双( Balicki和Nantka-Namirski最初报道了三氟甲基)-3,5-吡啶二羧酸酯,但后来证明是4-芳基-2,6-二羟基-2,6-双(三氟甲基)-3,5 -哌啶二羧酸酯。
