Procedure
Three hundred milligrams of 10,11-dihydrodibenzo[b.f]thiepin-2-acetic acid are dissolved in an excess of 1N aqueous sodium hydroxide and the resultant solution is buffered with 0.3 g. of ammonium chloride. The buffered solution is added to a solution of 200mg. of calcium carbonate in 1N aqueous hydrochloric acid. The formed precipitate is collected by filtration, washed consecutively with water, dimethoxyethane and ether, to yield calcium 10,11-dihydrodibenzo[b.f]thiepin-2-acetate.
