2,4-Dichloropyrimidine (250 mg, 1.678 mmol), 3-methoxy-1-propanol (0.193 ml, 2.014 mmol), and cesium carbonate (929 mg, 2.85 mmol) were combined in DMF (5 ml). The suspension was heated to 80° C. for 15 h. The mixture was allowed to cool to room temperature, diluted with brine and extracted with EtOAc (3×). The organic layer was dried over Na2SO4 and concentrated in vacuo. Purification via flash chromatography (5-15% EtOAc:Hexanes) gave 2-chloro-4-(3-methoxypropoxy)pyrimidine (112 mg, 33%) as a colorless oil. MS ESI: [M+H]+ m/z 203.
