Reaction Steps
Methyl {2-[4-(2-chloroethoxy)phenyl]-1,3-oxazol-4-yl}acetate 151 (0.55 g, 1.86 mmol, 1 eq) is reacted with 2-methylpyrrolidine (0.28 ml, 2.79 mmol, 1.5 eq) in the presence of potassium carbonate (0.77 g, 5.58 mmol, 3 eq) and a catalytic quantity of sodium iodide in refluxing acetonitrile (20 ml). After 45 h, the solvent is evaporated, the residue is then taken up in ethyl acetate and washed two times with an aqueous solution of sodium hydrogenocarbonate. The organic layer is dried over magnesium sulfate, filtered and concentrated under vacuum. Purification by chromatography over silicagel (eluent: dichloromethane/methanol/ammonia 97:2.7:0.3) affords 0.3 g of methyl (2-{4-[2-(2-methylpyrrolidin-1-yl)ethoxy]phenyl}-1,3-oxazol-4-yl)acetate i52.
