-78 °C

In a three neck flask equipped with stirring bar under N2 atmosphere tropine (1 g, 4.24 mmol) was suspended in (anhydrous) THF (15 mL). The mixture was cooled to −78° C. and BuLi (2M in THF) (5.53 ml, 1.2 eq) was added dropwise and the mixture was allowed to warm to 25° C. over 30 minutes. To the reaction mixture 2,4,-dichloro-6-morpholin-4-yl-[1,3,5]triazine (996 mg, 4.24, mmole) was added and allowed to stir overnight. For work up, ether (100 mL) was added. The organic layer was washed with water (20 mL) and brine (20 mL) and dried over MgSO4, filtered and the solvents were removed to obtain a colorless oil. Further purification by flash-chromatography using CH2Cl2/MeOH/NH3 (15:1:0.1) gave the product as white solid (600 mg, 42% yield); MS (ESI) m/z 340
