以乙醇为溶剂,硼氢化钠还原丁苯那嗪合成了二氢丁苯那嗪(DTBZ)。从体积比为5:1的二氯甲烷和乙醇的混合溶液中获得适合于X射线分析的晶体。晶体为单斜晶系,空间群P21/c,晶体学参数:a = 15.0129(14),B = 12.5677(12),c = 9.7715(9),β = 98.556(2)°,μ = 0.078 mm−1,V = 1823.1(3)3,Z = 4,Dc = 1.164 g/cm 3,F(000)= 696,T = 296(2)K。X-射线衍射分析和手性HPLC表明,该方法制备的DTBZ由(2 R,3R,11bR)和(2S,3S,11bS)两种对映体组成。
The dihydrotetrabenazine (DTBZ) was synthesized by reduction of tetrabenazine with sodium borohydride in ethanol. Crystals suitable for X-ray analysis were obtained from a mixed solution of dichloromethane and ethanol in a five-to-one volume ratio. The crystal is monoclinic, space group P21/c with crystallographic parameters: a = 15.0129(14) , b = 12.5677(12) , c = 9.7715(9) , β = 98.556(2)°, μ = 0.078 mm−1, V = 1823.1(3) 3, Z = 4, Dc = 1.164 g/cm3, F(000) = 696, T = 296(2) K. The X-ray analysis and the chiral HPLC show that the DTBZ prepared by our method consists of (2R,3R,11bR) and (2S,3S,11bS) enantiomers.
