PROCESS FOR PREPARATION OF DIETHYLENETRIAMINEPENTAACETIC ACID DERIVATIVE, AND DIETHYLENETRIAMINEPENTAACETIC ACID DERIVATIVE

The objective of the present invention is to provide a process for simple and efficient preparation of an intermediate compound to synthesize a gadolinium complex having a substituent for improving a retention property in blood time and specificity to an

A highly selective mono-C-allylation of DTPA pentaethyl ester

A highly selective mono-C-allylation of pentaethyl diethylenetriaminepentaacetate was achieved with allyl bromide and potassium carbonate via a newly developed elaborate procedure based on Stevens rearrangement. It is contrastive that the conservative one
