The preparation of the amides 3 from a wide variety of nonactivated esters 1 and secondary amines 2 has been achieved at 8 kbar and around 45 deg C; scope and limitations are discussed.The method was also successfully applied for the aminolysis of alkyl 2-arylsulfinylacetates 7 that are relatively sensitive to heat. - Key Words: Aminolysis/ High-pressure synthesis

Triazolopyridine is proposed as a new derivative for the location of branches and double bonds in fatty acids.It is compared with previously used derivatives and found to be clearly superior to the pyrrolidide and slightly superior to the β-picolinyl ester with regard to the structure-specific fragmentation pattern.It is prepared by reacting the activated acid with 2-hydrazinopyridine followed by cyclization.
