Reaction Steps

2 mL of dioxane and 1.8 mL of a solution of hydrochloric acid in dioxane (4M) are added to a 25 mL round-bottomed flask containing 85 mg of 43 (0.24 mmol). The mixture is stirred for 4 h at RT under argon. The dioxane is concentrated, and taken up in 10 mL of isopropyl ether. The solid formed is disintegrated with isopropyl ether. 60 mg of amine 44 (cream-coloured solid) are obtained after filtration in the hydrochloride form.
