Reaction Steps
The title compound was prepared in accordance with the general method of Example 108(C), from 3-bromo-1-methyl-1H-pyrazole (100 mg, 0.62 mmol) and 2-but-3-ynyl-benzo[d]thiazole (233 mg, 1.24 mmol, Example 35(A)). The crude residue was purified by flash chromatography (cyclohexane/AcOEt 7:3) to yield 35 mg (0.13 mmol, 21%) of 2-(4-(1-methyl-1H-pyrazol-3-yl)but-3-ynyl)benzo[d]thiazole as a brown semi-solid.
