Electric Literature of 3469-00-9, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 3469-00-9, name is Methyl Diphenylacetate, This compound has unique chemical properties. The synthetic route is as follows.
General procedure: 4.2 General procedures: A. Microwave. Neat samples of amine (1.00 mmol) and carboxylic derivative (methyl ester or acid, 1.00 mmol) and DABAL-Me3 (202 mg, 0.8 equiv) were placed in a 5 mL microwave vial and dry THF added (1 mL) under a blanket of argon. For coupling partners containing acidic hydrogens additional DABAL-Me3 (total of 410 mg, 1.6 equiv) was used. The vial was promptly capped and placed in a CEM Discover microwave reactor. After irradiation (290 W, 130 C, 8 min) and programmed cool down (ca. 20 min). The reactions were quenched by cautious addition of HCl (2 M, 4 mL) or aqueous solutions of Rochelle salt (saturated potassium sodium tartrate, 4 mL) (CARE: methane liberated). Extraction with dichloromethane, drying (MgSO4) and evaporation frequently provided the pure products directly. If purification was required column chromatography 3:2 to 2:3 hexane:EtOAc was used for amides lacking highly polar functional groups (CH2Cl2 with 2 % v/v MeOH was used for amides bearing pendant amines, alcohols and other polar functional groups).
The chemical industry reduces the impact on the environment during synthesis Methyl Diphenylacetate. I believe this compound will play a more active role in future production and life.
