*2.3. General Procedure for Mechanochemical Synthesis*

Mechanochemical experiments were carried out via liquid-assisted grinding (LAG) using a Retsh MM200 ball mill (Retsch, Haan, Germany) operating for 30 min at a 25 Hz frequency using methanol as a solvent.

Synthesis of DIC–ADE: A mixture of DIC (74.1 mg, 0.25 mmol) and ADE (33.80 mg, 0.25 mmol) in a 1:1 stoichiometric ratio was placed in a 10 mL stainless-steel jar along with 100 μL of methanol and two stainless-steel balls of 5 mm diameter.

Synthesis of DIC–CYT: A mixture of DIC (74.1 mg, 0.25 mmol) and CYT (22.20 mg, 0.25 mmol) in a 1:1 stoichiometric ratio was placed in a 10 mL stainless-steel jar along with 100 μL of methanol and two stainless-steel balls of 5 mm diameter.

Synthesis of DIC–ICT: A mixture of DIC (74.1 mg, 0.25 mmol) and ICT (22.20 mg, 0.25 mmol) in a 1:1 stoichiometric ratio was placed in a 10 mL stainless-steel jar along with 100 μL of methanol and two stainless-steel balls of 5 mm diameter.
