Procedure
Mix 2-(2-tert-butyl-5-[7-(3-trifluoromethyl-pyridin-2-yl)-quinazolin4-ylamino]-phenoxy}-ethanol (24 mg, 0.05 mmol) and triethyl amine (6 mg, 0.06 mmol) in dichloromethane 1 ml and add methanesulfonyl chloride (6 mg, 0.05 mmol). Stir the solution at room temperature for 1 hour and evaporate to dryness. Re-dissolve the residue in acetonitrile (2 ml), transfer to a sealed tube, add potassium carbonate (13 mg, 0.1 mmol) and L-proline methyl ester (13 mg, 0.1 mmol) and heat the mixture at 80° C. for 8 hours. Partition the residue between ethyl acetate and sodium bicarbonate solution and extract with further ethyl acetate. Dry the combined extracts (MgSO4) and concentrate under reduced pressure. Purify the residue by flash chromatography on silica gel (ethyl acetate) to give the title compound.
