The isolated crude free base, weight 4.0 grams, was dissolved in 150 ml of acetone and added to stirred boiling solution of 3.5 grams of fumaric acid in 800 ml of acetone. After cooling, the precipitate of the title compound was collected, washed with acetone, and dried. The yield was 4.1 grams; mp 178° C.-180° C. was decomposition.
