실험 절차

A mixture of 5-chloro-7-morpholin-4-yl-thiazolo[5,4-d]pyrimidine-2-carbaldehyde (400 mg, 1.40 mmol), 4-azetidin-3-ylthiomorpholine-1,1-dioxide (321 mg, 1.69 mmol) and 4 Å powdered molecular sieves (600 mg) in DCE (20 mL) was stirred at room temperature for 4 h before the addition of sodium triacetoxyborohydride (595 mg, 2.80 mmol). The reaction mixture was stirred for 65 h then filtered through celite, washing with DCM. The organic phase was washed with brine (×1) and concentrated in vacuo affording 5-Chloro-2-[3-(1,1-Dioxo-1-thiomorpholin-4-yl)azetidin-1-ylmethyl]-7-morpholin-4-ylthiazolo[5,4-d]pyrimidine as an orange powder (572 mg, 89%). LCMS (Method H): RT 2.43 min [M+H]+ 459.2
