Reaction Steps

A solution of {1-[hydroxy-(N-hydroxycarbamimidoyl)-methyl]-propyl}-carbamic acid tert-butyl ester (2) (2.5 g, 10 mmol) in dichloromethyl (125 ml) was treated with benzoic acid (1.36 g, 11 mmol), EDCI (2.14 g, 11 mmol), HOBT (1.37 g, 10 mmol) and triethylamine (1.35 ml, 11 mmol) and stirred at room temperature overnight. Reaction mixture was washed with saturated sodium bicarbonate solution and then water and dried over Na2SO4. Solvent evaporated under reduced pressure, crude purified by mplc eluting with 1% triethylamine in 2:3 v/v ethyl acetate and heptane mixture to give yellow solid (850 mg); MS: MH+ 352.
