1-(3,4-二氢-2H-色烯-2基)甲胺盐酸盐

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 5.0 g (25 mmol) of 2-aminomethylchroman hydrochloride are dissolved in 50 ml of pyridine; 5.6 g (35 mmol) of cycloheptanecarbonyl chloride are added dropwise to this solution. After 1 hour at 50° C., the mixture is concentrated and the residue is partitioned between water and toluene/ethyl acetate 1:1. The organic phase is filtered over silica gel. The desired product is eluted with toluene/ethyl acetate 5:1. The amide obtained after concentration is further reacted directly. the mixture is concentrated the residue is partitioned between water and toluene/ethyl acetate 1:1 The organic phase is filtered over silica gel The desired product is eluted with toluene/ethyl acetate 5:1

实验步骤: 20.27 g of 2-aminomethylchroman hydrochloride are introduced into 130 g of methanol, and 20.4 g of a 30% sodium methoxide solution in methanol are subsequently added. 20.43 g of 5-(4-fluorophenyl)pyridine-3-carbaldehyde are added to the white suspension at 35° C., and the mixture is stirred for 1.5 hours before 4.20 g of sodium borohydride are added in portions. After 15 hours, 56.4 ml of water are added, and the pH of the mixture is adjusted to pH 2 using 37% hydrochloric acid. After the suspension has been cooled to 0° C., the crystals are filtered off, washed with methanol and dried under reduced pressure, giving 28.2 g of 2-[5-(4-fluorophenyl)-3-pyridylmethylaminomethyl]chroman hydrochloride (64% yield). are subsequently added are added in portions the crystals are filtered off washed with methanol dried under reduced pressure
