A mixture of 66 mg (0.25 mmol) of (E) 4-chloro-2-[2-(3-chloro-phenyl)-vinyl]-6-methyl-pyrimidine and 0.89 g (12.5 mmol) pyrrolidine was heated at 60° C. for 1.5 h after which time the reaction was completed according to TLC analysis (CH2Cl2/EtOAc: 4/1). The excess pyrrolidine was removed in vacuo and the residue was purified on a silica gel chromatography column (eluted with CH2Cl2/EtOAc: 4/1). The purified fractions were combined, evacuated in vacuo, the solid residue was triturated with ether and filtered off by suction to give (E)-2-[2-(3-Chloro-phenyl)-vinyl]-4-methyl-6-pyrrolidin-1-yl-pyrimidine (61 mg, 80%) as an off-white crystalline solid. ISP mass spectrum, m/e: 300.3 (M+1 calculated for C17H18ClN3: 300).
