Benzonitrile, 4-bromo- → 4-[4-(2,2,4,6,7-Pentamethyl-2,3-dihydro-1-benzofuran-5-yl)piperazin-1-yl]benzonitrile

Participants

Reaction Steps

By using 1-(2,2,4,6,7-pentamethyl-2,3-dihydro-1-benzofuran-5-yl)piperazine (2.74 g, 10.0 mmol) synthesized in Reference example 61 and 4-bromobenzonitrile (2.73 g, 15 mmol), the reaction was carried out in the same manner as Example 23 to synthesis the title compound 700 mg (yield 19%). Melting point was 255 to 257° C. (ethanol).
