YieldReaction ConditionsOperation in experiment
40% With 1,4-diaza-bicyclo[2.2.2]octane; 1,10-Phenanthroline; copper dichloride; In water; at 80℃; for 24h;Inert atmosphere; General procedure: A mixture of 2-iodophenol 1 (0.3 mmol), isothiocyanate 2 (0.36 mmol, 1.2 equiv), DABCO (0.6 mmol, 2.0 equiv), CuCl2·H2O (0.015 mmol, 5 mol %), 1,10-phenanthroline (L-1, 0.006 mmol, 2 mol %), was stirred in water (3 mL) at 80 oC for 24h (indicated by TLC). The mixture was cooled in an ice-water bath. The crude was filtered and washed with saturated brine (2 x 10 mL), then washed with water (10 mL), and dried under vacuum to obtain product 3 in almost pure form (except for 3d, 3k, 3q, 3w, 3y and 3z needing to pass through a small plug of silica). In the case of liquid products (3g3m and 3s), the crude reaction mixture was diluted with saturated water (10 mL), and extracted with EtOAc (3 x 10 mL). The combined organic layers were dried on anhydrous MgSO4, followed by the evaporation of the solvent to obtain the crude product, which was passed through a small plug of silica to obtain pure product.

YieldReaction ConditionsOperation in experiment
87% With montmorillonite K10 Clay; In acetonitrile; at 20℃; for 3h; General procedure: A round bottom flask containing commercially available montmorillonite K10 (10 molpercent) was placed in an oven at 120-130°C for 30 minutes and then it was cooled to room temperature under nitrogen protection. To the activated montmorillonite K10 was added isothiocyanate (3.4 mmol) and <strong>[25475-67-6]3-aminoisoquinoline</strong> (3.4 mmol) followed by acetonitrile (2 mL) at room temperature. The resulting suspension was stirred at room temperature for 1-3 hour. When the reaction was completed (detected by TLC), ethyl acetate (30 mL) was added and the catalyst was filtered off to recover. The organic layer was washed with water (3×30 mL), and finally with half saturated brine, dried over anhydrous Na2SO4 and concentrated by rotary evaporator. Finally, the residue was purified by recrystallization from ethanol.
