PROCEDURE

实验过程

A 4N-hydrogen chloride ethyl acetate solution (0.57 ml) was added to an ethyl acetate solution (1 ml) of 2-nitro-N-(2-pyridin-3-ylethyl)-N-[3-(1,3,3,5-tetramethyl-2,4-dioxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-7-yloxy)propyl]benzenesulfonamide (236 mg), and stirred at room temperature for 1 minute. The precipitated insoluble matter was collected by filtration, washed with ethyl acetate, and dried to thereby obtain 163 mg (yield: 65%) of 2-nitro-N-(2-pyridin-3-ylethyl)-N-[3-(1,3,3,5-tetramethyl-2,4-dioxo-2,3,4,5-tetrahydro-1H-benzo[b][1,4]diazepin-7-yloxy)propyl]benzenesulfonamide hydrochloride as a white powder.
