실험 절차

To a suspension of 5-chloro-7-morpholin-4-ylthiazolo[5,4-d]pyrimidine-2-carboxylic acid (301 mg, 1.0 mmol) in DCM (6 mL) was added oxalyl chloride (847 μL, 10.00 mmol) and the resulting mixture allowed to stir at r.t. for 1 h then concentrated in vacuo and azeotroped with toluene. The resulting yellow solid was suspended in a mixture of DCM (6 mL) and NEt3 (418 μL, 3.00 mmol) at 0° C. before the addition of 4-azetidin-3-ylmorpholine (142 mg, 1.00 mmol). The resulting mixture was warmed to r.t. after 1 h then stirred for a further 30 min. The reaction mixture was partitioned between DCM and H2O, the organic phase dried (Na2SO4) and concentrated in vacuo. The resulting residue was triturated with EtOAc and dried in vacuo affording the title compound as an off-white solid (269 mg, 63%)._LCMS (method H): RT 2.19 min [M+H]+ 425.3
