Procedure

A mixture of 4,6-dichloro-2-methoxy-pyrimidine (0.41 g, 2.3 mmol), C-(2,3-dihydro-benzofuran-2-yl)-methylamine (0.52 g, 3.47 mmol), and NaHCO3 (0.97 g, 12 mmol) in EtOH (7 mL) is heated to reflux for 3 h. The mixture is diluted with water (8 mL), filtered, washed (water). The solid is dissolved in EtOAc, dried (MgSO4), filtered, and concentrated in vacuo to afford (6-chloro-2-methoxy-pyrimidin-4-yl)-(2,3-dihydro-benzofuran-2-ylmethyl)-amine (0.5 g) as a solid. LCMS: RT=2.59 minutes; MS: 292 (M+H).
