Participants

Reaction Steps

To a solution of 4-bromo-2-fluoro-1-nitrobenzene (500 mg, 2.27 mmol) and tert-butyl 3-aminopyrrolidine-1-carboxylate (390 mg, 2.27 mmol) in DMSO (5 mL) was added DIPEA (351 mg, 2.72 mmol) and the solution stirred in a sealed bottle at room temperature for 16 h. After LCMS analysis indicated completion of the reaction, the solution was diluted with water (100 mL) and DCM (100 mL). The organic layer was washed by water (30 mL×2) and brine (30 mL) and dried over anhydrous Na2SO4 before being filtered and concentrated to yield the desired product (670 mg Yield 80%). The material was used in the next step without further purification. LCMS (m/z): 386.1 (M+1).
