制备方法与用途

化学性质
纯品为白色结晶,工业品呈黄色片状,熔点在102~104℃之间。它易溶于乙醇、丙酮和苯等常用有机溶剂,并且也能溶解于水。该物质对皮肤有轻微的刺激作用。

用途
1-甲基-5-氨基吡唑-4-羧酸乙酯,又称1-甲基-4-乙氧基羰基-5-吡唑胺,是除草剂吡嘧磺隆的重要中间体。

生产方法
其制备过程如下:首先在反应釜中加入氰乙酸乙酯、原甲酸三乙酯以及催化剂和乙酸,加热后开始回流蒸出生成的乙醇。随后继续升温至130~155℃,维持6小时进行反应。反应结束后,减压蒸除原甲酸三乙酯,残留物转入吡唑胺反应釜中,加入乙醇并冷却至约0℃,再滴加甲肼乙醇溶液,升温后回流1小时,随后蒸发掉乙醇,并添加甲苯,冷却结晶后过滤、干燥得成品。

    Novel and potent calcium-sensing receptor antagonists: Discovery of (5R)-N-[1-ethyl-1-(4-ethylphenyl)propyl]-2,7,7-trimethyl-5-phenyl-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine-3-carboxamide monotosylate (TAK-075) as an orally active bone anabolic agent
    摘要:
    The calcium-sensing receptor antagonist (CaSR) has been recognized as a promising target of anabolic agents for treating osteoporosis. In the course of developing a new drug candidate for osteoporosis, we found tetrahydropyrazolopyrimidine derivative 1 to be an orally active CaSR antagonist that stimulated transient PTH secretion in rats. However, compound 1 showed poor physical and chemical stability. In order to work out this compound's chemical stability and further understand its in vivo efficacy, we focused on modifying the 2-position of the tetrahydropyrazolopyrimidine. As a result of chemical modification, we discovered (5R)-N-[1-ethyl-1-(4-ethylphenyl)propyl]-2,7,7-trimethyl-5-phenyl-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine-3-carboxamide monotosylate 10m (TAK-075), which showed improved solubility, chemical stability, and in vivo efficacy. Furthermore, we describe that evaluating the active metabolite is important during repeated treatment with short-acting CaSR antagonists. (C) 2011 Elsevier Ltd. All rights reserved.
