Methyl p-toluenesulfonate → HCID 86593320, compound

Participants

Reaction Steps

2-methyl-6-(benzothiazol-2-yl)-benzothiazole (44 mg, 0.156 mmol) was stirred for 5 h at 90° C. in melted methyl tosylate (660 mg, 3.5 mmol). After being allowed to cool to room temperature, the product was precipitated by addition of acetone and collected by filtration. The precipitate was washed with acetone and allowed to dry over night. This gave the product as green crystals. Yield: 51 mg, 70%. 1H NMR (DMSO): δ 2.28 (s, 3H, —CH3), 3.20 (s, 3H, CH3), 4.24 (s, 3H, —CH3), 7.11 (d, J=7.2, 2H, ArH), 7.46 (d, J=7.2, 2H, ArH), 7.55 (t, J=7.6, 1H, ArH), 7.62 (t, J=7.6, 1H, ArH), 8.14 (d, J=8, 1H, ArH), 8.25 (d, J=8, 1H, ArH), 8.45 (d, J=8.8, 1H, ArH), 8.59 (d, J=8.8, 1H, ArH), 9.24 (s, 1H, ArH). HR-FAB-MS m/z Found: 297.067 C16H13N2S2 (M+): requires M, 297.052.
