실험 절차

A mixture of 2-chloro-5-formyl-N-(tricyclo [3.3.1.13,7]dec-1-ylmethyl)-benzamide (0.244 g, Example 1b), 2-(2-aminoethylamino)-ethanol (0.154 g), p-toluenesulfonic acid (0.005 g) and toluene (30 ml) were refluxed together under Dean-Stark conditions for 3hs, cooled and concentrated under reduced pressure to give an oil. This was dissolved in ethanol (30 ml) and cooled to 0 C. under a nitrogen atmosphere. Solid sodium borohydride (0.030 g) was added portionwise to this and the mixture stirred at room temperature for 30 min. The mixture was concentrated under reduced pressure and the residue purified by column chromatography over silica gel (eluting with 7:3:0.3 dichloromethane/methanol/35% aqueous ammonia) to give the free base. This was dissolved in methanol (10 ml) and treated with 4M hydrochloric acid in dioxane (4 ml) to give a solid precipitate. This was filtered off and washed with diethyl ether to afford the title compound as a solid (0.165 g).
