Analyzing the synthesis route of 344329-76-6

344329-76-6, The synthetic route of 344329-76-6 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.344329-76-6,Tetrahydro-2H-pyran-4-carboxamide,as a common compound, the synthetic route is as follows.

Example 156 A suspension of Example B5 (0.596 g, 4.61 mmol) in dioxane (15 mL) was treated with oxalyl chloride (0.820 mL, 9.69 mmol), stirred at RT for 10 min, then heated to 80¡ã C. for 4 h. The mixture was cooled to RT, concentrated to dryness, treated with Example A13 (0.200 g, 0.703 mmol), pyridine (0.120 mL, 1.481 mmol) and THF (5 mL) and stirred at RT overnight. The mixture was concentrated to dryness, the residue suspended in MeCN and sonicated, and the resulting solid was collected via filtration, suspended in water, stirred for 15 min, then again collected via filtration. The solid was treated with MTBE, stirred for 1 h and then collected via filtration to afford N-((5-((2-(2-methylthiazol-5-yl)pyridin-4-yl)oxy)pyridin-2-yl)carbamoyl)tetrahydro-2H-pyran-4-carboxamide (110 mg, 33percent). 1H NMR (400 MHz, DMSO-d6): delta 11.06 (s, 1H), 10.89 (s, 1H), 8.41 (d, J=5.6 Hz, 1H), 8.32 (s, 1H), 8.28 (d, J=2.9 Hz, 1H), 8.09 (d, J=9.0 Hz, 1H), 7.75 (dd, J=9.0, 2.9 Hz, 1H), 7.60 (d, J=2.4 Hz, 1H), 6.82 (dd, J=5.8, 2.4 Hz, 1H), 3.88 (m, 2H), 3.34-3.25 (m, 3H), 2.65 (s, 3H), 1.72 (m, 2H), 1.62-1.59 (m, 2H); MS (ESI) m/z: 440.2 (M+H+).
