실험 절차

A mixture of 2-chloro-5-formyl-N-(tricyclo [3.3.1.13,7]dec-1-ylmethyl)-benzamide (0.244 g, Example 25b), N-isopropyl-1,3-propanediamine (0.211 g), p-toluenesulfonic acid (0.005 g) and toluene (30 ml) were refluxed together under Dean-Stark conditions for 3 h. The mixture was cooled and concentrated under reduced pressure to an oil. This was dissolved in ethanol (30 ml) and cooled to 0° C. under a nitrogen atmosphere. Solid sodium borohydride (0.040 g) was added portionwise and the mixture stirred at room temperature for 30 min, then concentrated under reduced pressure and the residue purified by column chromatography over silica (eluting with 9:1:0.1 dichloromethane/methanol/35% aqueous ammonia) to give the title compound (0.015 g) and a by-product (see Example 27).
