Versuchsvorschrift

To a solution of 3-[1-phenylmethyl-2-pyrrolidinyl]phenol (0.64 g) in dry tetrahydrofuran (20 ml) was added 1,1-carbonyldiimidazole (0.61 g) at ambient temperature, under nitrogen. The reaction mixture was stirred for 48 hrs, glacial acetic acid (0.50 ml) was added followed by a solution of 4-(2-aminoethyl)morpholine (0.43 ml) in tetrahydrofuran (1.0 ml) and glacial acetic acid (0.20 ml). After 3 hrs, the reaction mixture was poured into saturated sodium bicarbonate solution and ether. The layers were separated, and the aqueous phase was extracted with ether (2 times). The combined organic extracts were washed with saturated sodium bicarbonate and brine, dried over anhydrous sodium sulfate, filtered, and the filtrate was concentrated. The residue was purified by radial chromatography, using ether as the eluent. The appropriate fractions were collected and concentrated to give 0.56 g (54%) of product. Recrystallization from ether/petroleum ether gave the analytical sample, mp 74°-77° C.
