Procedure

8-(3,4-Dichlorobenzyl)-7-[(ethoxycarbonyl)amino]-5,6,7,8-tetrahydronaphthalen-2-yl trifluoromethanesulfonate (250 mg, 0.475 mmol), zinc cyanide (139 mg, 1.187 mmol) and tetrakistriphenyl palladium (82 mg, 0.071 mmol) in dimethylformamide (5 mL) were heated in the microwave at 120° C. (100 W) under stirring for 35 min. The solvent was evaporated in vacuo and the crude product was partitioned between ethyl acetate (40 mL) and water (30 mL). The aqueous layer was extracted with ethyl acetate one more time (20 mL) and the combined organic extracts were dried (Na2SO4) and concentrated in vacuo. The crude product (460 mg) was purified by flash chromatography (dichloromethane to dichloromethane:methanol=100:1, silica gel). Yield: 109 mg (0.270 mmol, 57%, colorless solid).
