Reaction Steps

To a solution of ethyl 1-methylnipecotate, 0.3 mL (1.65 mmol) in 10 mL of dioxane was added a solution of 118 mg (4.95 mmol) of lithium hydroxide in 10 mL of water. The solution was stirred for 1.5 hours at rt. then was acidified to pH=1 with 5N HCl. The mixture was concentrated to dryness and carried on without further purification. IS (MS) 144.1 (M+1).
