Reaction Steps
A mixture of 328 mg (1 mmol) of 2-(2-methoxyphenylmethyl) -3-(2-chloroethyl)-4(3H)-quinazolinone and a 70% aqueous ethylamine solution (0.6 ml) in ethanol (10 ml) was heated at 80 ° C. W for 8 hours in a sealed tube. The solvent was distilled off under reduced pressure and to the residue thus obtained there was added a 10 % aqueous potassium carbonate solution, followed by extraction with dichloromethane. The thus obtained dichloromethane solution was dried over magnesium sulfate and then concentrated. The resulting residue was purified by silica gel column chromatography (eluent: 1% ethanol-chloroform) to obtain 55 mg (16%) of 2-(2-methoxyphenylmethyl)-3-(2-ethylaminoethyl)-4(3H)-quinazolinone as an oily substance. Subsequently, the thus obtained quinazolinone was dissolved in ether (3 ml) and to the resulting solution was added a 10% HCl/ethanol solution. The precipitated crystals were collected by filtration to obtain the hydrochride of the captioned compound.
