To a suspension of 3-(4-(3-chloro-4-fluorophenylamino)-2-(pyridin-3-yl)quinazolin-6-yl)propan-1-ol (0.25 g, 0.61 mmol) and triethylamine (0.17 ml, 1.22 mmol) in CH2Cl2 (10 mL) was added methanesulfonyl chloride (0.057 ml, 0.73 mmol). The mixture was stirred at room temperature for 1 h. Water (10 mL.) was added to the mixture and stirred for a while. The resultant precipitate was collected by filtration and washed with CH2Cl2 and dried to give 0.27 g of 3-(4-(3-chloro-4-fluorophenylamino)-2-(pyridin-3-yl)quinazolin-6-yl)propyl methanesulfonate as pale yellow solid (91%), which was used without further purification.
