Versuchsvorschrift
Into a solution of 760 mg of ethyl N-methanesulfonyl-formimidate in diethyl ether (20 ml) was dropped 0.95 g of 4-amino-1-benzylpiperidine at room temperature. After stirring for 2 hours, the crystals thus precipitated were filtered and washed with diethyl ether to thereby give 580 mg of N2-methanesulfonyl-N1-(1-benzylpiperidin-4-yl)formamidine as colorless needles. These crystals were dissolved in 30 ml of methanol and 500 mg of 10% palladium-carbon was added thereto. Then the resulting mixture was stirred in a hydrogen atmosphere under atmospheric pressure for 1 hour followed by filtration through celite. After distilling off the solvent under reduced pressure, the residue was recrystallized from acetone/ethyl acetate to thereby give 310 mg of the title compound as colorless needles.
