✦ Synopsis
Abstract
JTT‐501 specifically labelled with ^13^C was obtained via a four‐step synthesis at an isotopic enrichment level of 99% and in 14% overall chemical yield starting from 4‐hydroxy‐[ring‐U‐^13^C~6~]benzaldehyde (3). The hydrogenation of [^13^C~6~]JTT‐501 over Pd/C gave [^13^C~6~]JTP‐20604 in 90% chemical yield. Copyright © 2003 John Wiley & Sons, Ltd.
