Reaction Steps

A mixture of 1.5 g (5 mmol) of (2,2-dimethyl-1,3-dioxan-5-yl)methyl 4-methylbenzenesulfonate and 10 mL (101 mmol) of cyclopentylamine is heated for 12 hours at 80° C. The medium is concentrated under reduced pressure and then taken up in 200 mL of Et2O, washed with water (2×50 mL) and then dried over Na2SO4 and concentrated under reduced pressure. 1 g of N-[(2,2-dimethyl-1,3-dioxan-5-yl)methyl]cyclopentanamine is obtained in the form of an oil, which is used without further purification in the following step.
