Reaction Steps

A solution of 2-bromo-5-methyl-nicotinic acid ethyl ester (0.4 g, 1.63 mmol) (synthesized according to Ponticello's procedure J. Org. Chem., 1978, 43, 2529-2535) in Et2O (10 mL) was dropwise added LiAlH4 (1.0 M in THF, 1.79 mL, 1.79 mmol) at −78° C. After the addition was completed, the suspension was stirred at −78 C for 1 h. EtOAc was carefully added at −78° C. and then water was dropwise added. The organic portion was brought to the usual work-up to give the product without further purification. 1H NMR (300 MHz, CDCl3) 8.13 (s, 1H), 7.68 (s, 1H), 4.73 (s, 2H), 2.33 (s, 3H).
