Reaction Steps

According to general procedure B, chlorobenzene (57 mg, 0.50 mmol) reacted with aniline (48 mg, 0.50 mmol) using 1 mol % of Pd(dba)2, 2 mol % of Ph5FcP(t-Bu)2, and sodium tert-butoxide (59 mg, 0.60 mmol) in toluene at 70° C. to give the title compound (73 mg, 86%) as a white solid. The coupling reaction of bromobenzene (158 mg, 1.00 mmol) with aniline (93 mg, 1.00mmol) occurred at room temperature over 4 h using 1 mol % of Pd(dba)2/Ph5FcP(t-Bu)2 to give the title compound (166 mg, 98%): 1H-NMR (400 MHz, CDCl3): δ 7.34 (t, 4H, J=7.8 Hz and 7.5 Hz), 7.14 (d, 4H, J=8.7 Hz), 7.00 (t, 2H, J=7.2 and 7.5 Hz), 5.74 (bs, 1H). 13C{1H}-NMR (100 MHz, CDCl3): δ 143.09, 129.32, 120.97, 117.78. GC/MS(EI): m/z 169 (M+).
