PROCEDURE

实验过程

A mixture of (3RS)-1,3-dihydro-3-(2-indolylcarbonylamino)-1-(2-bromoethyl)-5-phenyl-2H-1, 4-benzodiazepine-2-one (0.3 g) and 1-methylpiperazine (3.0 ml) was stirred for 4.0 hours at room temperature and diisopropyl ether (20 ml) was added thereto. The resultant precipitates were collected by filtration and dissolved in diluted hydrochloric acid. The solution was adjusted to pH 7 with an aqueous solution of sodium bicarbonate and the resultant precipitates were collected by filtration to give (3RS)-1,3-dihydro-3-(2-indolylcarbonylamino)-1-[2-(4-methyl-1-piperazinyl) ethyl]-5phenyl-2H-1,4-benzodiazepine-2-one (0.20 g).
