Participants

Reaction Steps

Prepared According to Procedure a Using 2-amino-5-chlorobenzoic acid (2.0 g, 11.7 mmol) and SOCl2 (2.2 mL, 29.2 mmol) in benzene (50 mL), followed by 2-chloroaniline (2.5 mL, 23.3 mmol) and CHCl3 (50 mL). The product was purified by recrystallization from MeOH to provide 1.72 g of a dark yellow solid (52%). 1H NMR (CDCl3) δ: 8.37 (dd, J=1.5, 8.3 Hz, 1H); 8.22 (br s, 1H); 7.48 (d, J=2.3 Hz, 1H); 7.42 (dd, J=1.5, 8.1 Hz, 1H); 7.31 (dt, J=1.4, 7.8 Hz, 1H); 7.22 (dd, J=2.4, 8.8 Hz, 1H); 7.09 (dt, J=1.5, 7.7 Hz, 1H); 6.67 (d, J=8.8 Hz, 1H); 5.56 (br s, 2H).
