Versuchsvorschrift

To a solution of 1-(3-quinolin-6-ylmethyl-3H-[1,2,3]triazolo[4,5-b]pyrazin-5-yl)-ethanone (100 mg, 0.33 mmol) in THF was added MeMgBr (0.260 mL, 0.362 mmol, 1.4M in toluene/THF) at 0° C. The reaction was allowed to stir for 16 hours at room temperature. The LC-MS showed a 1:1 ratio (ketone:alcohol), so another equivalent of the MeMgBr was added and the reaction was stirred for an additional 16 hours. The crude reaction was concentrated and purified by a reverse-phase C-18 preparative eluting of ACN—H2O with 0.1% acetic acid HPLC to give 2-(3-quinolin-6-ylmethyl-3H-[1,2,3]triazolo[4,5-b]pyrazin-5-yl)-propan-2-ol (4 mgs, 4% yield).
