Procedure

To 0.98 g of the acid of Example 9 partially dissolved in 10 ml water is added, with stirring 0.18 g calcium carbonate. After 10 minutes, the solution is filtered, the filtrate concentrated and the residue treated with ether to give a crystalline product which is dried at 40° C. and 25 mm pressure to give 0.88 g of the calcium salt mp 265° C.
