실험 절차

A mixture of 2-chloro-9-methyl-6-morpholin-4-yl-9H-purine-8-carbaldehyde (235 mg, 0.82 mmol), 4-azetidin-3-ylmorpholine (122 mg, 0.86 mmol) and 4 Å powdered molecular sieves (300 mg) in DCE (8 mL) was stirred at room temperature for 3 h before the addition of sodium triacetoxyborohydride (346 mg, 1.63 mmol). The reaction mixture was stirred for 65 h then filtered through celite, washing with DCM. The organic phase was washed with brine and concentrated in vacuo. The resulting residue was purified by column chromatography (Si—PCC, MeOH:EtOAc, 0-20%) affording 2-Chloro-9-methyl-6-morpholin-4-yl-8-(3-morpholin-4-ylazetidin-1-ylmethyl)-9H-purine as a cream solid (165 mg, 49%). LCMS (Method A): RT 2.22 min [M+H]+ 408.2
