실험 절차

Pyridine diamide 2 was prepared according to the general procedure described in Example 8 using 2-(aminomethyl)pyridine (0.015 mol), 2-chloro-N,N-diethylacetamide (0.045 mol), diisopropylethylamine (0.060 mol) and dimethoxyethane (25 mL). The product was isolated from the methylene chloride extraction of the basic aqueous layer. The residue was distilled (140° C., 0.10 mm) to afford 3.7 g of pure product.
