実験手順

1.73 g of 3-amino-1,3-dihydro-5-(2,6-dimethoxy-4-methylphenyl)-1-methyl-1,4-benzodiazepin-2-one are dissolved in 30 ml of dimethylformamide in the presence of 1.42 g of BOC-D-phenylalanine, followed by cooling to 5° C. and addition of 1.07 ml of triethylamine and then 2.4 g of BOP. The reaction mixture is allowed to return to room temperature and is left stirring overnight. It is then poured into water and extracted with ethyl acetate. The organic phase is washed with water, separated out after settling of the phases, dried over Na2SO4, filtered and concentrated under vacuum. An oily residue of 2-tert-butoxycarbonylamino-N-[2,3-dihydro-5-(2,6-dimethoxy-4-methylphenyl)-1-methyl-2-oxo-1H-1,4-benzodiazepin-3-yl]-3-phenylpropionamide, obtained in quantitative yield, is used as it is for the following step (Compound 16).
