Reaction Steps

To a solution of 2-(2-amino-4-chloro-phenoxy)-1-[4-(4-fluoro-benzyl)-2-methyl-piperazin-1-yl]-ethanone (0.066 g, 0.17 mmol) in methylene chloride (2 mL) at ambient temperature was added N-methylmorpholine (0.025 mL, 0.23 mmol), 3-tert-butoxycarbonylamino-propionic acid (0.044 g, 0.23 mmol) and O-benzotriazole-1-yl-N,N,N′, N′-tetramethyluronium hexafluorophosphate (0.076 g, 0.20 mmol). The resulting solution was stirred at ambient temperature for 60 hours, then concentrated. Radial chromatography (2 mm plate) gave the title compound (0.114 g)
