실험 절차

0.24 mL (3.04 mmol) methanesulphonic acid chloride are added to a solution, cooled to 0° C., of 800 mg (2.53 mmol) {4-[4-(5-bromo-pyridin-2-yl)-but-3-ynyl]-phenyl}-methanol in 17 mL DCM and then a solution of 0.52 mL ethyldiisopropylamine in 3 mL DCM is added dropwise. The mixture is stirred for a further 30 min at 0° C., 0.51 mL (6.08 mmol) pyrrolidine is added, the reaction mixture is heated to RT and kept at this temperature for 5 h. To complete the reaction another 0.26 mL (3 mmol) pyrrolidine are added and stirred for 1 h at RT. The mixture is evaporated down i.vac., combined with 10 mL water and 20 ml EtOAc, acidified with 1 M HCl and the organic phase is separated off. The aqueous phase is made alkaline with 2 M Na2CO3 solution, extracted with 20 mL EtOAc, the organic phase is separated off and dried over Na2SO4. After the desiccant and solvent have been eliminated the desired product is obtained.
