Reaction Steps

0.86 mL (5.05 mmol) ethyldiiopropylamine are added to a solution of 600 mg (2.53 mmol) 5-bromo-2-chloro-3-nitropyridine and 0.32 mL (2.53 mmol) 1-(2-aminoethyl)-pyrrolidine in 3 mL n-butanol. The reaction is heated to 50° C. and stirred for one hour at this temperature. The solvent is eliminated i.vac. and the residue is combined with 40 mL water and acidified with 1 M HCl. The aqueous phase is extracted with 20 mL EtOAc and the aqueous phase is then made alkaline with saturated K2CO3 solution. The aqueous phase is extracted with 40 mL EtOAc. The organic phase is dried over Na2SO4 and the solvent is eliminated i.vac.
