YieldReaction ConditionsOperation in experiment
With triethanolamine; In 1,4-dioxane; To a cooled (15°-20° C.) Solution of Compound 2 (1.5 g) in dioxane (2 mL) is added dropwise a solution of Compound 5 (1.2 g) and TEA (1.1 mL) in dioxane (2.6 mL) at a rate which allows the temperature to be maintained below 20° C. The reaction is stirred at ambient temperature under N2 for 20 hours and the precipitate that is formed is filtered.

YieldReaction ConditionsOperation in experiment
59.3% With sodium methylate; In methanol; for 3h;pH Ca. 6.8;Reflux; General procedure: Methanolic solution of CuCl2 2H2O (1.5 mmol) was added to a methanolic solution of 3-(diphenylphosphino)-propionic acid (L) (1.5 mmol) followed by the addition of a previously prepared methanolic solution of sparfloxacin (SFLH) (1.5 mmol) in presence of CH3ONa (1.5 mmol). The pH of the reaction mixture was adjusted to ～6.8. The resulting solution was refluxed for 3 h on a water bath, followed by concentrating to half of its volume. A fine, green amorphous product obtained was washed with ether/hexane/chloroform and dried in vacuum desiccators. The proposed reaction for the synthesis of complexes is shown in scheme 1 .

YieldReaction ConditionsOperation in experiment
64.18% In methanol; for 10h;pH Ca. 6.8;Reflux; General procedure: To a hot solution of VOSO4 (2) (5 mmol) in MeOH(25.0 mL), previously prepared methanolic solution ofligand 3-(diphenylphosphino)-propionic acid (1) (5 mmol)was added, with constant stirring. Then, alkaline methanolicsolution of ciprofloxacin (5 mmol) was added. The pH of thereaction mixture was adjusted to*6.8. The resulting greensolution was refluxed for 10 h and concentrated under vacuum.Upon addition of Et2O, a green solid precipitate wasobtained, which was collected by filtration, washed withEt2O and dried in vacuo (Gajera et al., 2015).
