-

Yield:2401-47-0 95%

Reaction Conditions:

in acetonitrile at 220; for 0.116667 h;Sealed tube;Microwave irradiation;Solvent;

Steps:

Reaction between 2-(dimethylamino)ethyl methyl carbonate 2 and phenol in ACN - Table 1, No.7

General procedure: Phenol (0.060 g, 0.637 mmol) was dissolved in ACN (3 mL) at room temperature in a 10 mL CEM pressure vessel equipped with a stirrer bar. 2-(Dimethylamino)ethyl methyl carbonate 2 (0.140 g, 0.955 mmol) was added and the vial was sealed and heated in a CEM Discover microwave synthesizer to 220 °C for 7 min. After cooling, a sample of the crude material was analysed by HPLC to define conversion and selectivity. Then, the reaction mixture was concentrated via rotavapor and it was purified via liquid-liquid extraction (EtOAc 50 mL / NaOH 5% aqueous solution 50 mL x 3). The organic phase was dried with sodium sulphate, filtered and concentrated under vacuum. The pure compound was isolated as a brown oil in 95% yield (0.100 g). Characterization of compound 3 was consistent with one reported in the literature.2
