Participants

Reaction Steps

5-Amino-2-(pyridin-2-ylmethyloxy)pyridine (D2, 1.36 g, 0.0068 mole) in dichloromethane (50 ml) was cooled to 0° C. under argon. Triethylamine (1.04 ml, 0.0075 mole) was added, followed dropwise by phenyl chloroformate (0.94 ml, 0.0075 mole) and the mixture was stirred at room temperature for 4 hours, washed with water, dried (Na2SO4) and evaporated in vacuo. The residue was chromatographed on silica gel, eluting with ethyl acetate to leave the title compound (1.9 g, 87%) as a solid.
