Application of 40061-54-9, These common heterocyclic compound, 40061-54-9, name is Ethyl 2-(2-chlorophenyl)acetate, 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.
EXAMPLE 35 2-(alpha-ethoxycarbonyl-2-chlorobenzylidene)-1-methylpyrrolidine Follow the procedure of Example 31 to obtain 73.8 g (93percent of theory) of the title compound (b.p. 129° to 0.008 mm of Hg) from 98.4 g of 2-dimethylamino-1-methyl-1-pyrrolinium-methylsulfate, 56.1 g of 2-chlorophenylacetic acid ethyl ester and a solution of 9.5 g of sodium in 190 ml of ethanol.
The synthetic route of 40061-54-9 has been constantly updated, and we look forward to future research findings.
