The downstream synthesis method of this compound is introduced below.
Preparation 46-Bromo-2,2-dimethyl-2H-pyrano[2,3-b]pyridin-4(3H)-one[00153]A solution of 3,5-dibromo-2-methoxypyridine (1 1 .4 g, 42.7 mmol) in dry diethyl ether is cooled to -65 C and treated with BuLi (19 mL 2.5 M solution in hexane, 47.5 mmol) under argon atmosphere. The mixture is stirred at -70 C for 0.5 h. A solution of 3-methylbut-2-enal (3.44 g, 40.9 mmol) in dry THF (10 mL) is added to the mixture, and stirring is continued for another 0.5 h at -70 C. The reaction mixture is then warmed to r.t. and quenched with a saturated solution of sodium bicarbonate (100 mL). After extraction with DCM (3 x 100 mL) the combined organic layers are dried over Na2S04 and concentrated under reduced pressure to yield 1 -(5-bromo-2-methoxypyridin-3-yl)-3- methylbut-2-en-1 -ol (1 1 g, 95%).
