Kiprianov, G. I. published the artcileSynthesis of some derivatives of β-phenylisopropylamine. I. Reaction of symmetric dihaloalkanes with β-phenylisopropylamine, COA of Formula: C6H12Br2, the publication is Ukrains’kii Khemichnii Zhurnal (1950), 16(No. 6), 620-6, database is CAplus.
Heating 5 g. (CH2Br)2 with 35 g. PhCH2CHMeNH2 (I) 5 hrs. at 130° gave 7.4 g. (CH2NHCHMeCH2Ph)2, b3 195-200°; di-HCl salt, m. 272-4°. Heating 37.5 g. I with 17 g. (CMe2Br)2 6 hrs. on a steam bath gave 5.6 g. PhCH2CHMeNHCMe2CMe:CH2, b7 135-43°; HCl salt, m. 173-4°; the free amine with Br yields a product m. 120-1°. Heating 67.5 g. I with 12 g. 1,2-dibromocyclohexane 7 hrs. at 100° and 4 hrs. at 120° gave 7.2 g. N-(1-(or 2-)cyclohexen-1-yl)-2-phenylisopropylamine, b3 130-5°; HCl salt, m. 186-9°. (CH2)3Br2 (10.1 g.) and 67.5 g. I kept 24 hrs. at room temperature gave 10 g. 1,3-bis(2-phenylisopropylamino)propane, b2 200-5°; di-HCl salt, m. 238-9°. Similarly (CH2)4Br2 gave 94% 1-(2-phenylisopropyl)pyrrolidine, b4 117-23°; HCl salt, m. 136-8°. (CH2)5Br2 gave 62% 1-(2-phenylisopropyl)piperidine, b4 115-17°; HCl salt, m. 215-16°. (CH2)6Br2 and I kept 24 hrs. at room temperature gave 58% 1,6-bis(2-phenylisopropylamino)hexane, b2 224°; picrate, m. 183-4°; di-HCl salt m. 253-4°.
