Crude 2-Bromo-1-(3a,6a-dihydro-thieno[3,2-b]thiophen-2-yl)-ethanone (2.48 mmol assuming complete conversion from starting material) was treated with Boc-proline and MeCN (25 mL). Triethylamine was added and the solution was stirred at RT for 1 h then concentrated. The crude residue was purified by silica column chromatography (14% to 35% EtOAc/Hex) to afford the title compound (595 mg, 61%).
