Versuchsvorschrift

To a light orange, homogeneous solution of ethyl 4-(3-(benzyloxycarbonylamino)-2-methylphenyl)-6-morpholino-9H-pyrido[3,4-b]indole-1-carboxylate (0.1705 g, 0.302 mmol) in methanol (3.59 mL) and THF (10.78 mL) was added LiOH (0.029 g, 1.208 mmol) in water (5.44 μL, 0.302 mmol). After 1.5 hr, the reaction was concentrated in vacuo. Water was added to the residue and acidified to pH ˜6 with 1 N aqueous HCl. The insoluble material was filtered and dried over Drierite to give the desired product (0.14098 g, 0.263 mmol, 87% yield) as an orange solid.
