84% | With sodium hydrogencarbonate In 1-methyl-pyrrolidin-2-one; water at 28 - 33℃; for 15 - 17 h; | A reactor was charged with 1-(2,3-dihydroxypropyl)-4-oxo-3-[(phenylmethyl)oxy]-1 ,4- dihydro-2-pyridinecarboxylic acid 6 (4.302 kg, 13.47 mol) followed by charging withNaHCO3 (1.69 kg, 20.09 mol) and 242 g of deionized water. To this was added 21.4 kg of NMP and the mixture was stirred and temperature brought to 28-35 0C. Dimethyl sulfate (2.34 kg, 18.30 mol) was added dropwise via an addition funnel to the reaction mixture over 1-3 hours keeping the temperature at 28-330C. The slurry was agitated at this temperature for 14 h. When deemed complete, the reaction mixture was cooled to 5 0C or below and the mixture was neutralized to pH 6 by the addition of HCI (561 ml_ of cone HCI in 2806 g of deionized water). The reaction vessel was slowly charged with cold 20percent brine solution composed of 8.7 kg NaCI, 20 kg of deionized water and 14.8 kg of ice at a maximum temperature of 100C. The mixture was agitated at 0-100C for 2.5 h. The slurry was filtered under vacuum and the cake washed with 15 kg of deionized water two times. The wet solid product was dried at 45-55 0C under vacuum until constant weight was obtained. The desired product methyl 1-(2,3-dihydroxypropyl)-4-oxo-3- [(phenylmethyl)oxy]-1 ,4-dihydro-2-pyridinecarboxylate 7 was obtained as a light yellow solid (3.77 kg, 99.42percent purity by HPLC, 84percent). 1H NMR(300 MHz, DMSO-d6) δ 7.60 (d, J = 7.5 Hz, 1 H), 7.36 (m, 5 H), 6.28 (d, J = 7.5 Hz, 1 H), 5.23 (d, J = 5.4 Hz, 1 H), 5.10 (Abq, J = 10.8 Hz, 2 H), 4.85 (m, 1 H), 3.98 (dd, J = 14.3, 2.4 Hz, 1 H), 3.79 (s, 3 H), 3.70 (dd, J = 14.3, 9.0 Hz, 1 H), 3.58 (m, 1 H), 3.23 (m, 1 H). |

55% | With sodium hydrogencarbonate In 1-methyl-pyrrolidin-2-one at 20℃; Inert atmosphere | Step E - Synthesis of Intermediate Compound A Into a 2-L 4-necked round-bottom flask purged and maintained with an inert atmosphere of nitrogen. This was followed by the addition of 3-(benzyloxy)-l-(2,3- dihydroxypropyl)-4-oxo-l,4-dihydropyridine-2-carboxylic acid If (200 g, 626.35 mmol, 1.00 equiv), NMP (1000 mL), sodium bicarbonate (158 g, 1.88 mol, 3.00 equiv), CH3I (133.5 g, 940.54 mmol, 1.50 equiv). The resulting solution was stirred overnight at room temperature. The reaction mixture was cooled to 0 °C with a water/ice bath. The resulting solution was diluted with a solution of NaCl (73 g) in 500 mL of H20. Then the pH value of the solution was adjusted to 4 with hydrogen chloride (cone). The reaction mixture was then stirred for another 2 hours. The solids were collected by filtration, washed with water (2x100 mL) and then dried in an oven in vacuo. This resulted in methyl 3-(benzyloxy)-l-(2,3-dihydroxypropyl)-4-oxo-l,4- dihydropyridine-2-carboxylate (117.6 g, 55percent yield) A as a white solid. |
