合成路线1
This compound can be obtained by several different ways: 1) By condensation of 4-ethylpropiophenone (I), formaldehyde (II) and piperidine (III) in refluxing isopropanol. 2) By reaction of 4-ethyl-alpha-methyl-beta-chloropropiophenone (IV) with (III) in refluxing ethanol. 3) By cyclization of 4-ethyl-alpha-methyl-beta-amino-propiophenone (V) with 1,5-dibromopentane (VI) in hot ethanol. 4) By a Friedel-Kraft's reaction of ethylbenzene (VII) with 3-piperidinoisobutyryl chloride (VIII) by means of AlCl3 at reflux temperature. 5) By condensation of 4-ethyl-alpha-methylenepropiophenone (IX) with (III) in ethanol.
