실험 절차

At RT NaH (60% dispersion in mineral oil, 4.6 mg, 0.12 mmol) is added to N-[6-amino-2-(2-phenylethynyl)pyridin-3-yl]benzenesulfonamide D5a (27 mg, approx. 0.07 mmol) in THF (0.6 ml). After stirring for 10 minutes dimethylsulfate (8 μl, 0.08 mmol) is added to the mixture and stirring continued for 1 h. The mixture is concentrated in vacuo and the product purified by RP HPLC. Yield: 16 mg (57%). HPLC-MS: M+H=364; tR=1.85 min (*Method—2).
