Reaction Steps
Following the procedure as described in PREPARATION 79A, and making non-critical variations using 2,3-dihydro-6H-[1,4]dioxino[2,3-f]indole-7,8-dione to replace 4-bromoisatin, 6-methyl-2,3-dihydro-6H-[1,4]dioxino[2,3-f]indole-7,8-dione was obtained (68%): 1H NMR (300 MHz, CDCl3) δ 7.09 (s, 1H), 6.74 (s, 1H), 4.41-4.38 (m, 2H), 4.27-4.24 (m, 2H), 3.08 (s, 3H); 13C NMR (75 MHz, CDCl3) δ; MS (ES+) m/z 220.2 (M+1).
