실험 절차

Similar to the synthesis of 1-(6-(4-pyrrazolyl)-2-benzothiazolyl)-3-ethylurea, a mixture of 1-(6-bromo-2-benzothiazolyl)-3-ethylurea, 4-chlorophenylboric acid, sodium bicarbonate, and Pd(PPh3)4 in DMF/water mixed solvent (5/1) was reacted to give the desired compound 0.020 g (18%). LC/MS 330 (M−1); LC retention time 2.70 min.
