Morpholine → HCID 86750823, compound

Participants

Reaction Steps

0.11 ml (1.3 mmol) of morpholine was added to 100 mg (0.13 mmol) of 1-[(2S,3S)-3-{N2 -[4-(N-bromoacetyl-N-methylamino)phenoxy]acetyl-L-asparaginyl}amino-2-hydroxy-4-phenylbutyryl]-N-t-butyl-L-prolinamide (prepared as described in Example 30), and the resulting mixture was allowed to stand for 4 days. At the end of this time, the reaction mixture was diluted with chloroform, and the diluted solution was washed with water. The solvent was then removed by distillation under reduced pressure, and the residue was purified by preparative thin layer chromatography, using a 16:4:1 by volume mixture of chloroform, methanol and 32% v/v aqueous acetic acid. The product was triturated with diethyl ether, to obtain 49 mg of the title compound as a colorless powder, melting at 114°-122° C.
