Procedure

To a suspension of 1-(2-chlorophenyl)-2-(4-methoxyphenyl)-4,5,6,7-tetrahydro-1H-pyrrolo[3,2-c]pyridine (Example 2, 80.0 mg, 0.236 mmol) and K2CO3 (97.9 mg, 0.708 mmol) in 2 mL DMF was added 4-fluorobenzonitrile (86.0 mg, 0.472 mmol) under argon. The mixture was heated at 130° C. with stirring for 48 h. The mixture was cooled to rt, water was added, and the mixture was extracted with ethyl acetate. The organic layer was dried over Na2SO4 and evaporated under reduced pressure. The crude product was purified on silica gel eluting with 1:3 EtOAc/hexanes to give a solid (44.7 mg, 43%): Rf=0.32 (1:2 EtOAc/hexanes).
