Procedure

A mixture of 4-(2-aminopyridin-3-yl)phenol (19.8 g), tert-butyldimethylchlorosilane (21.8 mL) and 1H-imidazol (8.69 g) in DMF (200 mL) was stirred at room temperature for 20 hr. To the mixture was added water, and the resulting precipitate was collected by filtration, and then washed with water to give the title compound (30.5 g) as a white solid.
