Reaction Steps
Intermediate 2 (724 mg, 1.7 mmol) was dissolved in THF (20 mL) and cooled to 0° C. before addition of triethylamine (362 μl, 2.6 mmol) and ethyl chloroformate (191 μL, 2 mmol). The reaction mixture was stirred at 0° C. for 1 hour and then partitioned between EtOAc and water. The organic layer was separated, washed with brine, dried (Na2SO4) and evaporated in vacuo. The resultant residue was triturated with EtOAc, filtered and the solid collected to yield the title compound as a white solid (49 mg).
