Procedure

To cyclopropylmethanamine (3.62 g, 50.9 mmol) in ethanol (90 mL) was added solid 4-chloropyrimidin-2-amine (6.00 g, 46.3 mmol). The reaction was stirred at reflux (100° C. oil bath) for 16 h. The reaction was cooled to room temperature and solvent was removed in vacuo. The product 237 obtained in quantitative yield. LCMS-ESI (POS), M/Z, M+1: Found 165.0, Calculated 165.1.
