Procedure

To a high-pressure reaction vial was added cis-6-(3-iodo-phenyl)-9-(3-piperidin-1-yl-propoxy)-1,2,3,5,6,10b-hexahydro-pyrrolo[2,1-a]isoquinoline (Example 32, 40.0 mg, 0.08 mmol), trimethylsilylacetylene (9.0 mg, 0.093 mmol), Pd(PPh3)2Cl2 (6.0 mg, 0.008 mmol), CuI (2.0 mg, 0.008 mmol), PPh3 (4.0 mg, 0.016 mmol), Et2NH (0.12 mL, 1.2 mmol), and DMF (0.1 mL). The sealed vial was placed in a 120° C. preheated oil bath for 30 min, cooled to rt, concentrated under a stream of nitrogen, and purified by reverse-phase HPLC to give 27.0 mg (47%) of the desired product as a TFA salt.
