Reaction Steps

An oven dried flask under N2 was charged with NaH (60% dispersion, 185 mg, 4.63 mmol). 5 mL of anhydrous THF was added followed by addition of 4-(tert-butyl-dimethyl-silanyloxymethyl)-5-methyl-pyridin-2-ylamine (9-6, 0.487 g, 1.93 mmol) and 2-chloro-5-cyanothiazole (1-2, 0.391 g, 2.70 mmol). The resulting solution was heated to reflux. After 1 hour the reaction was allowed to cool to room temperature and was then diluted with water. The pH was adjusted to 7 with 1 M HCl. The resulting precipitate was filtered and washed with water to afford 9-7.
