Procedure

A solution of 32 g of N-benzyloxycarbonyloxysuccinimide in 100 ml of tetrahydrofuran is reacted with 15 g of 6-amino-1-hexanol in 30 ml of 50% methanol:tetrahydrofuran. The reaction mixture is stirred overnight at room temperature, and poured into water. The resulting mixture is extracted with methylene chloride and the organic layer is washed with sodium chloride solution, dried over anhydrous magnesium sulfate. The magnesium sulfate is filtered and the solvent is removed by evaporation. The product is recrystallized from ethyl acetate/ether to provide N-(benzyloxycarbonyl)-6-amino-1-hexanol, mp 81.5°-83° C. having the following formula: ##STR31##
