(1-ethylpiperidin-4-yl)methanol

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 2-(Butyloxy)-8-(methyloxy)-1H-purin-6-amine (300 mg, 1.264 mmol), (1-ethyl-4-piperidinyl)methanol (362 mg, 2.53 mmol) and tributylphosphine (0.624 ml, 2.53 mmol) were dissolved in THF (12 ml). 1,1′-(Azodicarbonyl)dipiperidine (638 mg, 2.53 mmol) was added and the reaction mixture stirred at rt overnight. The solvent was removed in vacuo and the residue purified by column chromatography, loading in dichloromethane and purified on Flashmaster II silica (Si) 20 g using a 0-100% ethyl acetate in cyclohexane+0-20% methanol (+1% Et3N) gradient over 30 mins. The appropriate fractions were combined and evaporated in vacuo. The material (300 mg) was dissolved in 1:1 MeOH:DMSO 3 ml and re-purified by Mass Directed AutoPrep (Method A). The solvent was dried under a stream of nitrogen in the Radleys blowdown apparatus to give the title compound as a clear gum (60 mg). LCMS (System A): tRET=0.57 min; MH+ 363 The solvent was removed in vacuo the residue purified by column chromatography, loading in dichloromethane purified on Flashmaster II silica (Si) 20 g over 30 mins evaporated in vacuo The material (300 mg) was dissolved in 1:1 MeOH DMSO 3 ml and re-purified by Mass Directed AutoPrep (Method A) The solvent was dried under a stream of nitrogen in the Radleys blowdown apparatus
