N-(3-methoxy-phenyl)-4-nitro-benzenesulfonamide (RK1-1-27D) I This compound was prepared according to the procedure described for compound 11a except using m-anisidine. Recrystallization from DCM/Hexanes obtained the required product as brown-yellow needles (202 mg, 73%). Mp=96-98° C.; 1H NMR (400 MHz, CDCl3) δ 8.29 (d, J=9.0 Hz, 2H), 7.94 (d, J=9.0 Hz, 2H), 7.16 (t, J=8.0 Hz, 1H), 6.73-6.70 (m, 2H), 6.60-6.58 (m, 2H), 3.76 (s, 3H).
