Reaction Steps

A mixture of N-benzyloxycarbonyl-O-methyl-isourea (II-OMe) (0.42 g, 2.0 mmol) and 1,8-diaminooctane (Ie) (0.72 g, 12 mmol) in toluene (3.5 mL) was stirred at 40° C. for 24 h and at 6° C. for 1 h. The crystals were collected by filtration. The white crystalline product was washed with toluene (3×1 mL) and dried (vacuum, 30°-35° C., 2 h). The yield of N-(8-aminooctyl)-N'-benzyloxycarbonyl guanidine (IIIe) was 0.32 g (50% in theory).
