At room temperature, 10.0 g of compound 5-(4-(4-(3-fluorobenzyloxy)-3-chloroanilino)-6-quinazolinyl)furan-2-formaldehyde, 6.5 g of compound N-(2-aminoethyl)methanesulfonamide hydrochloride, and 14.6 g of triethylamine in the mixture of dichloromethane/methanol (3:1) were stirred overnight, then cooled with ice-bath to 0° C., and 1.4 g of sodium borohydride was added at that temperature. The mixture was warmed to room temperature, stirred overnight, saturated sodium bicarbonate was added to quench the reaction, and extracted with ethyl acetate. The organic phase was washed with saturated sodium chloride solution, dried over anhydrous sodium sulfate, and subjected to a column chromatography to obtain 5.7 g of the desired product, yield 45.0%.
