Procedure
(RK2-063-03)I This compound was prepared according to the procedure for compound 11a except using 2-methoxy-4 nitrobenzenesulfonyl chloride. Recrystallization from DCM/Hexanes obtained the required product as brown crystals (202 mg, 79%). Mp=127-129° C.; 1H NMR (400 MHz, CDCl3) δ 8.03 (d, J=8.8 Hz, 1H), 7.85-7.88 (m, 2H), 7.14-7.11 (m, 2H), 7.06-7.04 (m, 2H), 6.76 (br s, 1H), 4.13 (s, 3H), 2.26 (s, 3H).
