Reaction Steps

A solution of 215 mg (0.88 mmol) 2,5-dibromobenzene, 100 mg (0.88 mmol) 3-(dimethylamino)-pyrrolidine and 0.60 mL (3.51 mmol) ethyldiisopropylamine in 0.5 mL n-butanol is stirred for 30 min in the microwave at 150° C. The solvent is eliminated i.vac. and the residue is taken up in 20 mL EtOAc and 10 mL water. The aqueous phase is acidified with 1 M HCl. The phases are separated and then the aqueous phase is made alkaline with 2 M Na2CO3 solution and extracted with 40 mL EtOAc. The organic phase is dried over Na2SO4 and the solvent is eliminated i.vac.
