Mix 3-[3-(3-bromo-propoxy)-phenyl]-thieno[2,3-d]isoxazole (0.250 g, 0.739 mmol), potassium carbonate (0.205 g, 1.48 mmol), 1-adamantanamine (0.560 g, 3.70 mmol) and acetonitrile (4.0 mL) and heat at 75° C., overnight. Cool the reaction mixture and filter through a Waters Sep-Pak (1 g) silica gel cartridge (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 from 40% ethyl acetate in dichloromethane to 100% ethyl acetate to 20% methanol in ethyl acetate to give the title compound (132 mg, 44% yield). Purity by LC/MS (APCI)=98%, [M+H]+=409.
