4-Hydroxy-.alpha.-[(3,4-methylenedioxyphenyl)isopropylaminomethyl]-3-(methy lsulfonylmethyl)benzyl alcohol having .beta.-adrenergic stimulant activity, particularly as a selective bronchodilator, is prepared from 4-hydroxyacetophenone by conversion to 3-methylsulfonylmethylacetophenone, bromination and conversion of this phenone to the phenylglyoxal and treatment of the resulting glyoxal derivative with 3,4-methylenedioxyphenylisopropylamine followed by simultaneous reduction of the imine and ketone moieties and catalytic hydrogenation to remove the benzyl group.
4-羟基-.alpha.-[(3,4-亚甲二氧基苯基)异丙胺甲基]-3-(甲磺基甲基)苯甲醇具有β-肾上腺素激动活性,特别是作为选择性支气管扩张剂,是通过将4-羟基苯乙酮转化为3-甲基磺酰基甲基苯乙酮,溴化和将该酮转化为苯甘醛,然后用3,4-亚甲二氧基苯基异丙胺处理所得的甘醛衍生物,随后同时还原亚胺和酮基团,并进行催化氢化以去除苄基而制备的。
