Procedure
The product was prepared analogously to Example 48.1c from 1.74 g (8.06 mmol) of 5-(4-chlorophenyl)-2-ethynylpyridine and 2.00 g (8.06 mmol) of 2-(4-iodophenyl)ethanol (24 at RT, triethylamine as base and acetonitrile as solvent). Yield: 1.80 g (67% of theoretical); C21H16ClNO (M=333.811); calc.: molpeak (M+H)+:334/336 (Cl); found: molpeak (M+H)+:334/336 (Cl).
