    • The invention relates to a process for the preparation of N-methyl-[3-phenyl-3-[4-(trifluoromethyl)-phenoxy]-propyl]-amine of the Formula (I) and pharmaceutically acceptable acid addition salts thereof by reaction of N,N-dimethyl-{3-phenyl-3-[4-(trifluoromethyl)-phenoxy]-propyl}-amine of the Formula (III) and ethyl chloro formate and hydrolysis and decarboxylation of the N-methyl-N-ethoxycarbonyl-{3-phenyl-3-[4-(trifluoromethyl)-phenoxy]-propyl}-amine of the Formula (II) and if desired salt formation which comprises carrying out the reaction of the compound of the Formula (III) and ethyl chloro formate in toluene or xylene or a mixture thereof at a temperature below 90 DEG C; removing the contaminations and by-products from the reaction mixture by treatment with a diluted acid; separating the organic phase which contains the urethane derivative of the Formula (II) and reacting said organic phase, without isolating the urethane derivative of the Formula (II), with an alkali hydroxide at the boiling point of the reaction mixture in the presence of water and optionally n -butanol; removing the inorganic compounds; and if desired converting the base of the Formula (I) thus obtained into a pharmaceutically acceptable acid addition salt thereof. The compounds of the Formula (I) are a known valuable antidepressant.
    • 本发明涉及通过反应制备式(I)的N-甲基 - [3-苯基-3- [4-(三氟甲基) - 苯氧基] - 丙基] - 胺及其药学上可接受的酸加成盐的方法 的式(III)的N,N-二甲基 - {3-苯基-3- [4-(三氟甲基) - 苯氧基] - 丙基} - 胺和氯甲酸乙酯,并且N-甲基-N- (II)的乙氧基羰基 - {3-苯基-3- [4-(三氟甲基) - 苯氧基] - 丙基} - 胺,如果需要,形成盐,其包括进行式(III)的化合物和 氯甲酸乙酯在甲苯或二甲苯或其混合物中在低于90℃的温度下反应; 通过用稀酸处理从反应混合物中除去污染物和副产物; 分离含有式(II)的氨基甲酸酯衍生物的有机相,并使所述有机相与所述式(II)的氨基甲酸酯衍生物在碱存在下在反应混合物的沸点下与碱金属氢氧化物反应而反应 和任选的正丁醇; 去除无机化合物; 并且如果需要,将由此获得的式(I)的碱转化为其药学上可接受的酸加成盐。 式(I)的化合物是已知的有价值的抗抑郁药。
