Procedure

To a solution of disodium bicyclo[2.2.1]heptane-2,3-dicarboxylate (22.6 g, 0.1 mol) in water (150 g) was added a solution of calcium chloride dihydrate (14.7 g, 0.1 mol) in water (100 g). The mixture stirred at 60° C. for 2 hours. The resulting white precipitate was filtered. The white powdery product was dried and milled (m.p. >300° C.).
