Procedure

To a solution of 3-amino-4,4-dimethylpentan-1-ol (2.00 g, 8.64 mmol) in ethanol (20 mL) was added racemic 2,6-dichloro-5-fluoro-pyridine-3-carbonitrile (1.65 g, 8.64 mmol) and 5 mL of N,N,-diisopropylethylamine. The solution was stirred at 75° C. for 12 hours and concentrated in vacuo. The residue was purified by silica gel chromatography (methylene chloride), yielding 2.2 g of 2-chloro-5-fluoro-6-(1-hydroxy-4,4-dimethylpentan-3-ylamino)pyridine-3-carbonitrile, 95a: LCMS Gradient 10-90%, 0.1% formic acid, 5 minutes, C18/ACN, RT=3.02 minutes (M+H) 286.16
