5,5-Dimethyldihydrofuran-2(3H)-one (0.433 mmol, 0.049 g) was stirred in toluene (5 mL). Trimethylaluminium (0.867 mmol, 0.867 mL, 1 M in heptane) was added and the reaction stirred for 10 minutes at room temperature. (4-Aminophenyl)(4-(4-(1,1,1,3,3,3-hexafluoro-2-hydroxypropan-2-yl)benzyl)piperazin-1-yl)methanone (0.433 mmol, 0.2 g) was added and the reaction heated to reflux for 1 hour then a drop of N,N-dimethylformamide was added. The reaction mixture was heated to reflux for 1 hour. The reaction mixture was quenched with water. Ethyl acetate was added and the layers separated. The organic phase was concentrated under vacuum and the resulting residue purified by acidic preparative HPLC to afford the desired compound (1 mg).
