Reaction Steps

A mixture of allyl-(2-chloro-pyridin-3-yl)-carbamic acid tert-butyl ester (8.03 g, 30 mmol), tetrabutylammonium chloride (9.4 g, 30 mmol), palladium acetate (673 mg, 3 mmol) and potassium carbonate (12.4 g, 3 mmol) in DMF (300 mL) is heated at 80° C. for 1.5 h. The reaction is quenched with DCM and washed with water. The organic layer is dried (Na2SO4), filtered and concentrated. The residue is chromatographed through silica gel eluting with 0-40% EtOAc in heptane to afford 3-methyl-pyrrolo[3,2-b]pyridine-1-carboxylic acid tert-butyl ester and 3-methylene-2,3-dihydro-pyrrolo[3,2-b]pyridine-1-carboxylic acid tert-butyl ester (1.58 g).
