Versuchsvorschrift

The mixture of N-(9-chloro-3,4-dihydro-2H-1,5-benzodioxepin-7-ylmethyl)-2-methylpropan-1-amine (600 mg), (±)-2-Methyl-3-[(2-methylpropan-2-yl)oxycarbonylamino]propanoic acid (200 mg), 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloride (475 mg) and of dimethyl aminopyridine (284 mg) in DCM (30 ml) was stirred overnight. The reaction mixture was partitioned between ethyl acetate and water (30 mL each). The aqueous layer was extracted with EtOAc (30 mL×2). The combined organic layer was washed with brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by flash chromatography on silica (33% ethyl acetate in hexane) to give (±)-2-Methyl-3-(methylpropan-2-yl)oxycarbonylamino-N-(9-chloro-3,4-dihydro-2H-1,5-benzodioxepin-7-ylmethyl)-N-isobutylpropanamide as a resin: MS (m+1)=455.5.
