methyl N-[2-(2-bromophenyl)ethyl]carbamate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 1.36 g of methyl[2-(2-bromophenyl)ethyl]carbamate and 5.2 g of phosphoric acid are stirred under an inert atmosphere at a temperature close to 150° C. The reaction mixture is cooled to a temperature close to 20° C., then it is hydrolysed with a mixture of water and ethyl acetate using ultrasound treatment. After decanting, the organic phase is washed with a saturated aqueous solution of sodium hydrogen carbonate, water, a saturated aqueous solution of sodium chloride, then concentrated using a rotary evaporator under reduced pressure (5 kPa). 0.105 g of 5-bromo-3,4-dihydroisoquinolin-1(2H)-one is obtained in the form of an amorphous beige solid. close to 150° C The reaction mixture is cooled to a temperature close to 20° C. After decanting the organic phase is washed with a saturated aqueous solution of sodium hydrogen carbonate, water a saturated aqueous solution of sodium chloride, then concentrated a rotary evaporator under reduced pressure (5 kPa)

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 5 g of 2-(2-bromophenyl)ethanamine and 10 g of potassium carbonate in 30 cm3 of anhydrous tetrahydrofuran are stirred under an inert atmosphere at a temperature close to 10° C. 2.5 cm3 of methyl chlorocarbonate in solution in 10 cm3 of tetrahydrofuran are poured into the reaction mixture. After returning to a temperature close to 20° C., the reaction mixture is heated for 2 h at the reflux of the solvent. The potassium carbonate is filtered and washed with tetrahydrofuran. The filtrate is concentrated using a rotary evaporator under reduced pressure (5 kPa). 3.43 g of methyl[2-(2-bromophenyl)ethyl]carbamate are obtained in the form of a colorless thick oil close to 10° C close to 20° C. the reaction mixture is heated for 2 h at the reflux of the solvent The potassium carbonate is filtered washed with tetrahydrofuran The filtrate is concentrated a rotary evaporator under reduced pressure (5 kPa)
