Reaction Conditions

Reaction Steps

To a stirring solution of 4-aminobiphenyl (9.53 g, 56.3 mmol) and triethylamine (5.70 g, 56.3 mmol, 7.85 mL) in methylene chloride (60 mL), cooled to 0° C., was added slowly isobutyryl chloride (6.0 g, 56.3 mmol, 5.90 mL). After stirring at 0° C. for 1 h, the mixture was diluted with methylene chloride (120 mL) and washed with 1N NaOH and saturated brine, then dried (MgSO4), filtered and concentrated. The residue was washed with ether and dried to provide the title compound as a pale yellow crystalline solid (9.83 g, 73%). 1HNMR (400 MHz, CDCl3/CD3OD) δ 7.58 (d, 2H), 7.50 (m, 4H), 7.40-7.25 (m, 3H), 2.55-2.49 (m, 1H), 1.18 (d, 6H).
