実験手順

To a solution of ethyl 4-(3-(benzyloxycarbonylamino)-2-methylphenyl)-7-morpholino-9H-pyrido[3,4-b]indole-1-carboxylate (0.3539 g, 0.627 mmol) in THF (17.4 mL) and MeOH (5.8 mL) was added a solution of lithium hydroxide hydrate (0.105 g, 2.507 mmol) in water (3 mL). After 1 hr, the reaction was concentrated in vacuo. Water (12 mL) was added, and the solution was acidified with aqueous 1N HCl to pH 5-6 by litmus paper. The precipitate was filtered, washed with water, dried over Drierite to give the desired product (0.286 g, 0.533 mmol, 85% yield) as an orange solid.
