Versuchsvorschrift

4-Iodo-2-trifluoromethylphenylamine (50 mg, 0.17 mmol), Zn(CN)2 (0.88 eq, 0.15 mmol, 18.00 mg), and Pd(PPh3)4 (0.1 eq, 0.02 mmol, 19.64 mg) were added in DMF. Zn(CN)2 (0.88 eq, 0.15 mmol, 18.00 mg) and Pd(PPh3)4 (0.1 eq, 0.02 mmol, 19.64 mg) were added into the reaction mixture. The reaction mixture was stirred for 12 hr. The reaction mixture was purified according to step 1 of Example 8 to give a title product as a yellow solid (31.4 mg, 99.28%).
