Reaction Steps

To a stirred solution of 4-fluoro-2-methoxy-1-nitro-benzene (Fluorochem; 2.57 g; 15 mmol) in DMA was 2-pyrrolidin-1-ylethanamine (Aldrich; 1.88 g, 16.5 mmol) followed by DIPEA (2.97 mL, 18 mmol). The mixture was heated at 80° C. for 20 hours, then cooled to room temp. The mixture was concentrated in vacuo, dissolved in DCM and purified by SCX (50 g SCX 2 column). The product was eluted from the column with 7N ammonia in methanol, concentrated in vacuo to give the title compound (53 mg) which was dissolved in Methanol as a 0.05 mmol solution and reduced using an H-cube hydrogenator. 10% Pd/C catalyst, 1 bar hydrogen (full hydrogen setting), 3 mL/min flow-rate at 50° C. The resultant solution was concentrated in vacuo, and the resultant material purified by column chromatography, eluting with 0-10% ammonia/methanol in DCM, to give the title compound as a solid.
