Synthetic Route of 14658-93-6, These common heterocyclic compound, 14658-93-6, name is 2-Hydroxy-N,N-dimethylacetamide, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
6.2a) dimethylcarbamoylmethyl 1′-{(R)-3-(4-benzyloxy-3,5-dimethyl-phenyl)-2-[4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carbonyloxy]propionyl}-1,4′-bipiperidinyl-4-carboxylate 30 mg (0.29 mmol) 2-hydroxy-N,N-dimethyl-acetamide were added at RT to a solution of 200 mg (0.25 mmol) 1′-{(R)-3-(4-benzyloxy-3,5-dimethyl-phenyl)-2-[4-(2-oxo-1,2,4,5-tetrahydro-1,3-benzodiazepin-3-yl)-piperidine-1-carbonyloxy]-propionyl}-1,4′-bipiperidinyl-4-carboxylic acid (Example 6.1a), 90 mg (0.28 mmol) TBTU and 80 muL (3.73 mmol) triethylamine in 1.8 mL DMF and this was stirred for 20 h at RT. The reaction mixture was poured onto saturated NaHCO3 solution, the precipitate formed was suction filtered and dried. Further purification was carried out by HPLC, the fractions containing the product were combined and lyophilised. Yield: 100 mg (47% of theory) ESI-MS: (M+H)+=851 Retention time (HPLC-MS): 3.9 min (method B)
The synthetic route of 14658-93-6 has been constantly updated, and we look forward to future research findings.
