✦ Synopsis

6-aminolevulinic acid-4J4C was built up from phthalimide using KI4CN as the radioactive starting material. This method avoids the Iess practical synthesis via g1ycineJ4C and its condensation with phthalic anhydride to aflord phthalylglycine-l-14C whose yield, based on K-'4CN, is thus considerably improved.

The work was aimed at finding whether the ratio of delta-aminolevulinic acid (ALA) and creatinine (Cn) concentration (ALAICn), presently used in occupational health practice for evaluation of lead exposure gives a better assessment of ALA excretion than uncorrected ALA concentration itself, as well
