Reaction Steps
Pyridine diamide 6 was prepared according to the general procedure described in Example 8 using 2-(aminomethyl)pryidine (0.010 mol), 2-chloro-N,N-dibutylacetamide (0.030 mol), diisopropylethylamine (0.030 mol) and dimethoxyethane (30 mL). The product was isolated from the methylene chloride extraction of the acidic aqueous layer. The product was made basic by extraction with aqueous NaOH. The organic solution was concentrated, and the residue was distilled (150°-200° C., 0.10 mm) to afford 3.6 g of product.
