실험 절차

36 μL (0.46 mmol) methanesulphonic acid chloride are added to a solution, cooled to 0° C., of 120 mg (0.38 mmol) {4-[4-(5-bromo-pyridin-2-yl)-but-3-ynyl]-phenyl}-methanol (Example 2.20a) in 5 mL DCM. A solution of 78 μL (0.46 mmol) ethyldiisopropylamine in 1 mL DCM is slowly added dropwise, the mixture is stirred for a further 30 min at 0° C., then 80 μL (0.92 mmol) of morpholine are added, the mixture is allowed to come up to RT and kept at RT for 2 h. The mixture is evaporated down i.vac., the residue is combined with 20 mL EtOAc and 10 mL water, acidified with 1 M HCl and the phases are separated. The aqueous phase is combined with 2 M Na2CO3 solution, extracted with 20 mL EtOAc and the organic phase is dried over Na2SO4. After the desiccant and solvent have been eliminated the product is obtained.
