[1-(pyrrolidin-1-ylmethyl)cyclopropyl]methanol

反応条件: temp:110.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: Thionyl chloride (1 mL, 13.7 mmol) was added to a solution of (1-pyrrolidin-1-ylmethyl-cyclopropyl)-methanol (1.45 g, 9.3 mmol) in toluene (20 mL) to give a pale brown suspension. The suspension was heated, 110° C., for ˜3 hrs. to give a dark brown suspension. The resulting suspension was allowed to cool and concentrated to a brown solid. Tritruation with diethyl ether (40 mL) gave the desired intermediate, 1-(1-chloromethyl-cyclopropylmethyl)-pyrrolidine hydrochloride as a brown powder 1.6 g, 82%. to give a pale brown suspension to give a dark brown suspension to cool concentrated to a brown solid

実験手順: Lithium aluminium hydride solution (20 mL, 1M) in THF was added slowly to a solution of 1-(pyrrolidine-1-carbonyl)-cyclopropanecarboxylic acid methyl ester (2.2 g, 11 mmol) in THF at 0° C. (ice/water), under a nitrogen atmosphere, and the resulting solution stirred for ˜3 hrs at room temperature. The solution was cooled, 0° C. (ice/water), and sodium sulphate decahydrate (4.9 g, 15 mmol) was added portion-wise to give a white suspension. Diethyl ether (25 mL) was added and the suspension stirred for ˜18 hrs. at room temperature. The resulting suspension was filtered, through celite, and the solids washed with diethyl ether (2×50 mL). The combined filtrates were concentrated to give (1-pyrrolidin-1-ylmethyl-cyclopropyl)-methanol as a pale yellow oil 1.45 g, 84%. was added portion-wise to give a white suspension the suspension stirred for ˜18 hrs at room temperature The resulting suspension was filtered, through celite the solids washed with diethyl ether (2×50 mL) The combined filtrates were concentrated
