303-26-4, 1-((4-Chlorophenyl)(phenyl)methyl)piperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Example 1 10 gr. (0.035 mole) of 1-[(4-chlorophenyl)phenylmethyl]piperazine, 8.8 gr. (0.0525 mole) of ethyl 2-chloroethoxyacetate and 50 ml. of triethylamine were introduced into a pressure vessel. The mixture was stirred at 135C for 10 hours. It was cooled to 20C and filtered. The filtrate was evaporated and then distilled at 10 mbar pressure in order to remove the excess of the unreacted ethyl 2-chloroethoxyacetate. The oily residue obtained is sufficiently pure for the preparation of cetrizine by hydrolysis. The residue was purified over a silica gel chromatographic column. 13 gr. of ethyl [2-[4-[(4-chlorophenyl)phenylmethyl]-1-piperazinyl]ethoxy]acetate is obtained as dark red oil (89.4% yield).
303-26-4, The synthetic route of 303-26-4 has been constantly updated, and we look forward to future research findings.
