Reaction Steps

Crude MTC product (MW 373.90, 10.0 g, ˜26.7 mmol) was fully dissolved in H2O (270 cm3). Ethylenediaminetetraacetic acid (EDTA) disodium salt dihydrate (MW 372.24, 1 g, 2.68 mmol, 0.1 equivalents) was added. The mixture was stirred at 65° C. for approximately 1 hour. The mixture was filtered by vacuum filtration. The filtrate was collected. Sodium chloride (NaCl, MW 57.96, 16 g, 0.276 mol, 10 equivalents) was added to the filtrate while stirring. The resulting precipitate was collected by vacuum filtration.
