실험 절차
3.4 mL of a solution of hydrochloric acid in dioxane (4M) are added to a 25 mL round-bottomed flask containing 160 mg of 37 (0.452 mmol). The mixture is stirred for 4 h at RT under argon. The dioxane is concentrated, and taken up in 15 mL of isopropyl ether. The solid formed is disintegrated. 113 mg of amine 38 (cream-coloured solid) are obtained after filtration in hydrochloride form.
