Versuchsvorschrift

A mixture of benzyl 4-(2-ethyl-2-hydroxybutyl)phenylcarbamate (6.30 g), 10% palladium carbon (5.0 g) and tetrahydrofuran (150 mL) was subjected to catalytic reduction under a hydrogen atmosphere at atmospheric pressure. The catalyst was removed by filtration, and the filtrate was concentrated to give 3-(4-aminobenzyl)-3-pentanol as colorless crystals (3.51 g, yield 95%). Recrystallization thereof from ethyl acetate-hexane gave colorless prism crystals. melting point: 85-86° C.
