Conditions

Temperature: 110 °C

Procedure

187 mg of (S)-4,6-dichloro-N-[1-(4-fluorophenyl)ethyl]pyrimidine-2-amine (Reference Example 1), 175 mg of 5-(trimethylstannyl)nicotinonitrile, 25 mg of copper iodide and 75 mg of tetrakis(triphenylphosphine)palladium were added in turn to 3 ml of degassed toluene, and the mixture was stirred at 110° C. for 17 hours under argon atmosphere. The reaction solution was purified by silica gel column chromatography to obtain 58 mg of (S)-5-{6-chloro-2-[1-(4-fluorophenyl)ethylamino]pyrimidin 4-yl}nicotinonitrile as colorless oil.
