Reaction Conditions

Reaction Steps

Mix 3-[3-(2-bromo-ethoxy)-phenyl]-thieno[2,3-d]isoxazole (0.324 g, 1 mmol), potassium carbonate (0.28 g, 2 mmol), 2-methoxybenzylamine (0.686 g, 5 mmol) and acetonitrile (anhydrous, 4 mL) and heat at 75° C. for 16.5 hours. Cool the reaction mixture and filter through a Waters Sep-Pak silica gel cartridge (1 g) using ethyl acetate. Combine the appropriate fractions and concentrate to give a residue. Purify the residue by column (10 g silica) chromatography using a step gradient of 60% ethyl acetate in heptane to 100% ethyl acetate to give the title compound (342 mg, 90% Yield). Purity by LC/MS (APCI)=99%, [M+H]+=381.
