YieldReaction ConditionsOperation in experiment
With toluene-4-sulfonic acid; at 130.0℃; for 1.0h; Example A1; 6-Bromo-2-methyl-oxazolo[4,5-b]pyridine; A solution of 20 g (106 mmol) 2-amino-6-bromo-3-hydroxy-pyridine and 0.05 g p-toluenesulfonic acid monohydrate in 22 ml triethyl orthoacetate is stirred at 13O0C for 1 h. After cooling to room temperature the reaction solution is diluted with ethyl acetate (150 ml) and extracted with water (3 x 150 ml). The combined organic phases are dried over MgSO4, filtered and concentrated in vacuo. Subsequent purification by crystallization from ethanol affords the title compound (19 g) as yellow-orange crystals. The mass spectrum shows the molecular peak MH+ at 213.2 and 215.2 Da.

YieldReaction ConditionsOperation in experiment
With potassium tert-butylate; In tetrahydrofuran; tert-butyl alcohol; at -50.0℃; for 1.0h; Example A2; 6-Bromo-2-[2-(4-methoxy-pyridin-2-yl)-vinyl]-oxazolo[4,5-b]pyridine; A stirred solution of 1.46 g (10.6 mmol) 4-methoxy-pyridine-2-aldehyde and 6.0 g (28.3 mmol) 6- bromo-2-methyl-oxazolo[4,5-b]pyridine (starting compound A1 ) in 2.8 ml tert-butanol and 11 ml absolute tetrahydrofuran is cooled to -5O0C. A solution of 1.55 g K-tert-butylate in 10 ml absolute tetrahydrofuran is slowly added to the reaction solution under stirring. After further stirring for 1 h, the reaction mixture is warmed to room temperature. For workup, the mixture is poured into a saturated aqueous NaHCO3 solution and then extracted three times with ethyl acetate. The combined organic phases are dried over MgSO4, filtered and concentrated in vacuo. Subsequent purification by silica gel chromatography [petrol ether/ethyl acetate (1/1 parts by volume)] affords the title compound (1.0 g) as yellow crystals of m.p. 159.80C.
