HCID 3088056, compound → 4-Amino-3-{2-[2-(ethylamino)ethyl]-3-oxo-2,3-dihydro-1H-isoindol-1-yl}benzonitrile--hydrogen chloride (1/2)

Participants

Reaction Steps

The same procedures as in Example 29 were repeated except for using 20 g of 2-cyano-11-hydroxy-5, 11-dihydro-6H-dibenz[b,e]azepin-6-one and 42 ml of N-ethylethylenediamine as the starting materials. Thus, 3-(2-amino-5-cyanophenyl)-2-(2-ethylaminoethyl)isoindolin-1-one (Compound 38) was obtained. After dissolving it in isopropanol, Compound 38 was treated with hydrogen chloride-ethanol solution and the solution was concentrated to dryness under reduced pressure. The obtained solid was crystallized from acetonitrile to give 2.3 g of 3-(2-amino-5-cyanophenyl)-2-(2-ethylaminoethyl)isoindolin-1-one dihydrochloride (Compound 38').
