Participants

Reaction Steps

Ethyl chloroformate (0.16 mL, 1.65 mmol) was added to a solution of 5-methoxy-8-ethyl-1,2,3,3a,8,8a-hexahydroindeno[1,2-c]pyrrole (from Example 48, Step B) (0.24 g, 1.1 mmol) in CH2Cl2 (6 mL) at 0° C. The resulting solution was stirred overnight at room temperature. The reaction mixture was quenched with aqueous HCl solution (20 mL, 1.0 M) and the product was extracted with EtOAc (3×10 mL). The combined organic extracts were dried over MgSO4 and concentrated. The crude product was purified by column chromatography (SiO2) using a 0-35% EtOAc-hexanes gradient to afford 40 mg (13%) of the subtitle compound. MS calculated for C17H23NO3+H: 290, observed: 290.
