Procedure

O-(1H-Benzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (200 mg, 0.52 mmol) was added to a solution of 3-dimethylaminopropionic acid hydrochloride (80 mg, 0.52 mmol) in dichloromethane (5 ml) and the solution was stirred for 15 minutes. The amine from example 4 (100 mg, 0.26 mmol) was added and the reaction mixture was stirred at room temperature for 18 hours. The mixture was partitioned between dichloromethane and aqueous sodium bicarbonate solution, and the layers were separated. The organic phase was dried over magnesium sulphate and evaporated under reduced pressure. The crude product was purified by column chromatography on silica gel using dichloromethane:methanol:0.88 ammonia (90:10:1), to afford the title compound as a white solid (110 mg).
