Reaction Steps

A mixture of 4,6-dichloro-2-methoxy-pyrimidine (0.27 g, 1.48 mmol), C-(4-methyl-3,4-dihydro-2H-benzo[1,4]oxazin-2-yl)-methylamine (0.22 g, 1.23 mmol), and NaHCO3 (0.62 g, 7.4 mmol) in EtOH (7 mL) is heated to reflux for 5 h. The mixture is concentrated in vacuo. The residue is partitioned between EtOAc and water, and extracted with EtOAc. The extracts are dried (Na2SO4), and concentrated to afford (6-chloro-2-methoxy-pyrimidin-4-yl)-(4-methyl-3,4-dihydro-2H-benzo[1,4]oxazin-2-ylmethyl)-amine (0.39 g). LCMS: RT=3.27 minutes; MS: 321 (M+H).
