Reaction Steps

A slurry of methyl 5-(4-chlorobenzyloxy)-2-pyridylcarbamate (0.75 g, 2.6 mmol) in 10% sodium hydroxide (20 ml) and methanol (40 ml) is heated to 90° under nitrogen gas. After 1 hour, 10 ml of 10% sodium hydroxide and 10 ml of methanol are added. Heating is continued, and after 2 hours, 10 ml more of methanol is added. The reaction is heated under reflux overnight. The reaction is then rotoevaporated, and chloroform and water are added. The residue is extracted with chloroform (4X). The combined chloroform extracts are washed with water until neutral and with brine, dried over calcium sulfate, filtered and rotoevaporated to yield 2-amino-5-(4-chlorobenzyloxy)pyridine.
