Procedure
This compound was made according to the General Method 14 (EXAMPLE 191) from 3-nitrobenzene boronic acid (673.2 mg, 3.82 mmol) and 4-bromo-3-methylaniline (710.2 mg, 3.82 mmol) to afford 540 mg (62%) of 4-amino-2-methyl-3'-nitrobiphenyl (structure 82 of Scheme XXI, where R1 =R3-5 =R6 =R8 =H, R2 =nitro, R7 =methyl). Data for 4-amino-2-methyl-3'-nitrobiphenyl: 1H NMR (400 MHz, acetone-d6) 8.13 (dd, J=7.5, 1.1, 1H), 8.09 (dd, J=3.9, 1.8, 1H), 7.73 (ddd, J=7.7, 1.6, 1.4, 1H), 7.66 (dd, J=8.0, 7.8, 1H), 6.99 (d, J=8.0, 1H), 6.60 (m, 1H), 4.73 (br s, 1H), 2.18 (s, 3H).
