A mixture of 0.400 g (1.98 mmol) of (4E)-4-[(dimethylamino)methylene]-1,4-dihydro-3(2H)-isoquinolinone and 0.414 g (2.18 mmol) of 4-(2-Pyrrolidin-1-yl-ethyl)-phenylamine in 4 mL of PhCH3 is heated at 110° C. for 2.5 h. The reaction is placed in a freezer and the precipitated material is collected, washed with cold PhCH3(2×) and Et2O and dried in vacuo to give 0.280 g (41%) of gold crystals: mp 169-173° C.
