Procedure

A solution of hexahydro-3,5-dioxo-1H-pyrrolizine-2-carboxylic acid (8.3 g, 0.1 mole) in dioxane (200 ml) at 0° C. is treated with 0.1N calcium hydroxide solution (100 ml, 0.1 mole) and the resulting solution of the calcium salt of hexahydro-3,5-dioxo-1H-pyrrolizine-2-carboxylic acid is concentrated at reduced pressure to yield the dry calcium salt of hexahydro-3,5-dioxo-1H-pyrrolizine-2-carboxylic acid.

Workup

  1. concentrationthe resulting solution of the calcium salt of hexahydro-3,5-dioxo-1H-pyrrolizine-2-carboxylic acid is concentrated at reduced pressure
