Reaction Steps
EX-5A) A solution of 2-amino pyridine (20.42 , 217.0 mmol) in dichloromethane 500 mL was cooled to 0° C. and treated with triethyl amine (36.29 mL, 260.4 mmol) and pivaloyl chloride (28.06 mL, 227.8 mmol). After 15 minutes, the reaction mixture was allowed to warm to room temperature and stir overnight. The reaction mixture was poured onto ice, and the organic layer was washed with saturated NaHCO3 (aq), and dried over Na2SO4. The volatile components were removed, and a brown oil was isolated. Crystallization with hexanes afforded 31 g of N-(pyrid-2-yl)-2,2-dimethylacetamide (EX-5A) as white crystals in 80% yield. Reference: Turner, J. A. J. Org. Chem, 1983, 48, 3401.
