Some common heterocyclic compound, 17564-64-6, name is 2-(Chloromethyl)isoindoline-1,3-dione, molecular formula is C9H6ClNO2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Recommanded Product: 2-(Chloromethyl)isoindoline-1,3-dione
0.45 g of potassium carbonate (1.1equiv) were added to a stirring solution of saccharin (500mg, 1.0equiv) in 20mL of N,N-dimethylformamide at room temperature. N-(Chloromethyl)phthalimide (0.54g, 1.0equiv) was added and the reaction stirred at 80C for 72h. The reaction was poured on ice. The aqueous phase was extracted with ethyl acetate (3×50mL), the organics were reunited, dried over sodium sulfate and evaporated in vacuo. Purification via column chromatography on silica gel (ethyl acetate-n-hexane 2:1) gave title compound as a white solid (0.61mg, 66% yield); mp 284-287C; IR numax 1725 (nu C=O), 1337 (nuas S=O), 1252 (nu C-N), 1166 (nus S=O), 727 (delta Csp2-H), 677 (delta Csp2-H) cm-1; 1H NMR (400MHz, DMSO-d6) delta 5.66 (2H, s, CH2), 7.90 (2H, m, 2×CHAr), 7.97 (m, 2H, 2×CHAr), 8.02 (1H, t, J=7.6Hz, CHAr), 8.07 (1H, t, J=7.6Hz, CHAr), 8.19 (1H, d, J=7.6Hz, CHAr), 8.28 (1H, d, J=7.6Hz, CHAr); 13C NMR (101MHz, DMSO-d6) delta 41.8 (CH2), 122.0 (Ar),124.1 (Ar), 126.0 (Ar), 126.15 (Ar), 131.6 (Ar), 135.6 (Ar), 135.9 (Ar), 136.7 (Ar), 137.1 (Ar), 157.75 (C=O), 166.9 (C=O).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 17564-64-6, its application will become more common.
