Versuchsvorschrift
[7-(2-tert-Butoxycarbonylamino-ethoxy)-1-(3,4-dichloro-benzyl)-1,2,3,4-tetrahydronaphthalen-2-yl]-carbamic acid ethyl ester (9.27 g, 17.3 mmol) example 1 was dissolved in CH2Cl2 (200 ml) and HCl in iPrOH (6N) was added. The reaction was stirred at RT over night after which a solid precipitates. To the reaction mixture diethyl ether was added and the precipitating HCl salt was separated by filtration to give the final product as a solid (5.85 g, 12.3 mmol, 72%).
