实验步骤: In analogy to the procedure described for the synthesis of 5-tert-butyl-3-(2-chloro-benzyl)-7-morpholin-4-yl-3H-[1,2,3]triazolo[4,5-d]pyrimidine (example 1, step c), the title compound was prepared from 5-tert-butyl-7-chloro-3-(2-chlorobenzyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine and [1,2]oxazinane and isolated as light-yellow gum (13.6 mg, 75%). MS (m/e): 387.4 (MH+).

实验步骤: 1,4-dioxaspiro[4.5]decan-8-one (358.5 mg, 2.3 mmol), and 1,2-oxazinane (200 mg, 2.3 mmol), and sodium triacetoxyborohydride (1.46 g, 6.9 mmol) were taken in acetonitrile and stirred for 18 h at room temperature. The mixture concentrated under vacuum and the residue basified with NaHCO3, saturated with solid NaCl and extracted with EtOAc/iPrOH (4:1) four times. Organic layer separated, dried over Na2SO4 and evaporated. Residue purified by silica column chromatography to give the title compound.
