Reaction Steps

(R)-5-((E)-2-pyrrolidin-3-ylvinyl)pyrimidine free base (189 mg, 1.077 mmol, freshly prepared) was dissolved in acetonitrile (5 ml). The solution was then treated with 1.1 eq. of an maleic acid solution (1M in tetrahydrofuran) at ambient temperature. The mixture was warmed up to 50° C. and cooled down slowly to ambient temperature overnight. The solid obtained was filtered and dried under suction before being analysed by XRPD, and 1H-NMR. The XRPD diffractogram of (R)-5-((E)-2-pyrrolidin-3-ylvinyl)pyrimidine mono-maleate Form I is shown in FIG. 7.
