Reaction Steps

3-Bromo-dihydro-furan-2-one (2.49 g, 15.1 mmol) and 2-(Boc-amino)ethanethiol (2.9 g, 16.5 mmol) were dissolved in 40 mL of CH3CN. Then K2CO3(4.14 g, 30 mmol) was added to the solution. Let it stir at 80° C. for 16 h. The solvent was evaporated to dryness and the residue was purified by column chromatography (PE/EtOAc=4/1) to 3.8 g of BOC protected Intermediate 29 as colorless oil. The previous compound (3.7 g, 14.16 mmol) was dissolved in 10 ml of EtOAc. Then 40 mL of 4N HCl/EtOAc was added to the solution. Let it stir at 25° C. for 2 h. The white solid was filtered and washed with PE to give 2 g of Intermediate 29.
