Reaction Steps
Guanidine carbonate (792 mg; 4.4 mmol) is suspended in a solution of 2-[2-(4-Chlorophenyl)-3-methoxymethoxypropoxy]-6-fluorobenzonitrile (769 mg; 2.20 mmol) in DMA, and heated to 135° C. for 8 hours. The solution is cooled to RT overnight and placed in a freezer at 4° C. for 24 hours. The resulting black solids are removed by filtration through paper. The filtrate is concentrated under vacuum, and purified by column chromatography (10% MeOH/EtOAc). The collected fractions are dried to give 209 milligrams of 5-[2-(4-chlorophenyl)-3-methoxymethoxy propoxy]-quinazoline-2,4-diamine.
