실험 절차

2 g (0.0057 M) of N-[5-(o-fluorophenyl)-2,3-dihydro-1-methyl-2-oxo-1H-1,4-benzodiazepin-7yl]-1-aziridinecarboxamide in 50 ml of tert.butanol are treated with 3 ml of 25% sulphuric acid. After 20 minutes, the mixture is made alkaline with 10% sodium bicarbonate solution and extracted several times with methylene chloride. The methylene chloride solution is dried over sodium sulphate, filtered and concentrated. The residue is purified on a 80 g silica gel column using ethyl acetate as the eluting agent and recrystallised from ethyl acetate. There is obtained 1-(2-tert.butoxyethyl)-3-[5-(o-fluorophenyl)-2,3-dihydro-1-methyl-2-oxo-1H-1,4-benzodiazepin-7-yl]urea which melts at 177° C.
