title: S-configuration of (+)-primaquine by X-ray analysis of the urea obtained with R-(+)-1-phenylethylisocyanate.
abstract: The S-configuration for (+)-primaquine prepared from the racemate by chemical resolution was established by solid-state X-ray analysis of the (+)-1-phenylethylurea obtained with R-(+)-1-phenylethylisocyanate.
