実験手順
Deprotection: The 1-(4,5-Dibromo-thiophen-2-ylmethyl)-1-(2,4-dimethoxy-benzyl)-3-[4-(2-methoxy-ethoxymethyl)-thiazol-2-yl]-urea was treated with TFA followed by the addition of a drop of anisole and a drop of water. Stirred overnight at ambient temperature. The volatiles were removed in vacuo and the crude material was purified by taking up in MeOH and filtering to remove insolubles. The filtrate was concentrated in vacuo, and the resulting solid titrated with ether to give the title compound. 1H NMR (400 MHz, DMSO): 10.70 (br s, 1H), 7.17 (br m, 1H), 7.00 (s, 1H), 6.88 (s, 1H), 4.42 (d, 2H), 4.37 (s, 2H), 3.55 (m, 2H), 3.45 (m, 2H), 3.24 (s, 3H). MS (ES+): M/Z 484, 486 and 488 (M+1).
