75% With ammonia In ethanolHeating / reflux To a solution of 2 (13.8g, 0.064mol) in ethanol (25mL) was added ammonia solution (5OmL) and refluxed overnight. The solvent was removed under reduced pressure, then taken into water and adjusted to pH 1 with concentrated hydrochloric acid. The aqueous mixture was washed with ethyl acetate (3x) and the pH was adjusted to pH 10 with sodium hydroxide (2M.). The aqueous phase was extracted with chloroform (3?), dried over anhydrous sodium sulfate, filtered, and evaporated under reduced pressure. Re-crystallisation from methanol/diethyl ether gave brown cubic crystals, mp 162-164°C.

75% With ammonia In ethanolReflux To a solution of 2 (13.8 g, 0.064 mol) in ethanol (25 mL) was added ammonia solution (50 mL) and refluxed overnight. The solvent was removed under reduced pressure, then taken into water and adjusted to pH 1 with concentrated hydrochloric acid. The aqueous mixture was washed with ethyl acetate (3.x.) and the pH was adjusted to pH 10 with sodium hydroxide (2 M.). The aqueous phase was extracted with chloroform (3.x.), dried over anhydrous sodium sulfate, filtered, and evaporated under reduced pressure. Re-crystallisation from methanol/diethyl ether gave brown cubic crystals, mp 162-164 °C.

64% With ammonia In ethanol; water at 20℃; Heating / reflux A clear solution of 3-(benzyloxy)-2-methyl-4H-pyran-4-one (150 g, 0.69 mol), ethanol (300 mL) and ammonium hydroxide (28.0-30.0percent solution, 690 mL, 10.5 mol) in a 2 L 3-necked round bottom flask equipped with a mechanical stirrer was heated to reflux for 5 h.
The reaction mixture was allowed to cool to room temperature, and a further 230 mL of ammonium hydroxide (3.5 mol) was added.
The resulting solution was heated to reflux for another 3.5 h, then allowed to cool to RT and stirred for overnight.
A solid product had separated, and was collected by suction filtration.
Thus, 95 g of 3-benzyloxy-2-methyl-1H-pyridin-4-one (64percent yield) was obtained as a first crop. HPLC Method 4 (Example 24), RT=10.7 min, HPLC purity (peak percent area): 99percent at λ=280 nm)).

43% With sodium hydroxide; ammonia In ethanol; water at 90℃; for 1 h; 2) The compound 2 (162, 2g, 750mmol) was dissolved in ethanol (-187ml), and aqueous ammonia (28percent, 974ml) and a 6N aqueous sodium hydroxide solution (150ml, O00mmol) were added. After the reaction solution was stirred at 90 °C for 1 hour, this was cooled to under ice-cooling, and ammonium chloride (58g, 10S0mmol) was added, To the reaction solution was added chloroform, this was extracted, and the organic layer was washed with an aqueous saturated sodium bicarbonate solution, and dried with anhydrous sodium sulfate. The solvent was distilled off under reduced pressure, isopropyl alcohol and diethyl ether were added to the residue, and precipitated crystals were filtered to obtain 3-benzyloxy-2-methyl- 1H-pyridine-4-one 3 (69.1g, 43percent) as a pale yellow crystal.NMR (DMSO-dfi)δ: 2.05(3H, s), 5.04(2H, a), 6 14(1H, d, J=7 0Hz), 7,31-7.42(5H, m), 7 46(1H, d, J=7.2Hz), 11.29(1H, brs).
2.3 g With ammonium hydroxide In water; acetonitrile at 80 - 90℃; for 18 h; Sealed tube To a solution of 3-(benzyloxy)-2-methyl-4H-pyran-4-one (2.3 g) in acetonitirle (5 ml) was added aq.N in seal tube. The reaction mixture was heated at 80-90°C for 18 h. After completion of reaction, the reaction mixture was cooled at RT and diluted with ethyl acetate. The organic layer was separated and further aqueous layer was extracted with 10percent MeOH in DCM. The organic layer was concentrated to afford 2.3 g of desired product. 1H NMR (DMSO-d6): δ2.0 (s, 3H), 5.0 (s, 2H), 6.20 (s, 1H), 7.20- 7.40 (m, 6H), 11.20 (br s, 1H); MS [M+H]+ : 216.13.
