PROCEDURE

实验过程

To a solution of methyl 2-(8-(benzo[d]thiazol-2-ylcarbamoyl)-3,4-dihydroisoquinolin-2(1H)-yl)-5-(3-hydroxypropyl)thiazole-4-carboxylate (0.5 g, 0.96 mmol) in DCM (10 mL) was added TsCl (182 mg, 1 mmol), TEA (97 mg, 1 mmol), and catalytic amount of DMAP. The mixture was stirred at rt for 4 hours. The mixture was diluted with EtOAc and washed with water, brine, dried over Na2SO4, and concentrated under reduced pressure to provide the desired product methyl 2-(8-(benzo[d]thiazol-2-ylcarbamoyl)-3,4-dihydroisoquinolin-2(1H)-yl)-5-(3-(tosyloxy)propyl)thiazole-4-carboxylate (8F) which was used without further purification. LC/MS (APCI): m/z 663.0 (M+H)
