Versuchsvorschrift

A 4M HCl solution (p-dioxane, 40 mL) containing 1-(cyclohexylamino)-1-(hydroxymethyl)cyclopentane (Method B4a; 1.9 g, 9.6 mmol) and SOCl2 (0.84 mL, 11.5 mmol) was heated to 70° C. for 18 h. The resulting mixture was cooled to room temp. and concentrated under reduced pressure to yield crude 1-(chloromethyl)-1-(cyclohexylamino)cyclopentane HCl salt (2.84 g), which was used in the next step without firer purification.
