実験手順

To a solution of p-aminobenzenethiol (125 mg, 1 mmol) in methanol (1 ml) was added MMTS (94 μl, 1 mmol) in a single portion. The reaction was stirred at RT under N2. After 2 hr, the solution was loaded onto an SCX column and eluted with methanol, followed by 1M ammonia in methanol. The basic eluents were concentrated in vacuo to a yellow oil. Chromatography (1:1 hexanes:CH2Cl2 with 1% isopropylamine) yielded 39a (140 mg, 82%) as a pale yellow oil. 1H NMR (250 MHz, CDCl3): δ 7.28 (d, J=8.6 Hz, 2H); 6.54 (d, J=8.6 Hz, 2H); 3.60 (broad s, 2H); 2.34 (s, 3H). Treatment with HCl/ether gave 5 mg of the HCl salt. Biological testing was performed on the acid salt. 1H NMR (400 MHz, d6-DMSO): δ 7.46 (broad s, 2H); 7.05 (broad s, 2H); 2.47 (s, 3H); 2.43 (s, 3H).
