Versuchsvorschrift

A solution of 3-{[5-(trifluoromethyl)-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-1,3-benzodiazol-2-yl]methyl}cyclobutane-1-carbaldehyde (190 mg, 0.46 mmol), (1R,2S,3R,5R)-3-{4-amino-7H-pyrrolo[2,3-d]pyrimidin-7-yl}-5-(aminomethyl)cyclopentane-1,2-diol (140 mg, 0.46 mmol) and MgSO4 (554 mg, 4.61 mmol) in DCE (10 ml) was stirred for 15 min. STAB (137 mg, 0.645 mmol) was then added to the reaction mixture and stirred. The reaction was monitored by LCMS, after which no amine was seen. Sat. NaHCO3 (20 ml) was added to the reaction mixture and stirred for 5 mins. Brine (10 ml) was added to the reaction mixture and the product was extracted with DCM (2×30 ml), dried over Na2SO4, filtered and evaporated. Purification by silica gel column chromatography, eluting with 7N NH3 in MeOH:DCM (1:99-5:95) gave the desired product as a pink foamy solid. The mixed fractions were combined and purified on a prep. TLC plate eluting with 7N NH3 in MeOH:DCM (2×4:96) to give a total of 170 mg, 53%.
