실험 절차

Similarly to Example 1, 0.37 g of 3-(4-methoxypyridin-2-yl)propionic acid (starting material A1), 0.49 g of 2,3-diamino-5-(2-methylpropyl)pyridine (starting material D1) and 5 g of PPA (5 hours at 140° C. and chromatography using dichloromethane/methanol 30:1) give 0.151 g of the title compound of m.p. 111–113° C. The mass spectrum shows the molecular peak MH+ at 311.3 Da.
