應(yīng)用
(R)-4-Boc-2-甲基哌嗪常常作為醫(yī)藥中間體,主要用于生產(chǎn)驅(qū)腸蟲藥磷酸哌嗪、枸櫞酸哌嗪,以及氟奮乃靜、強(qiáng)痛定、利福平。(R)-4-Boc-2-甲基哌嗪溶于乙醇,加入冰醋酸攪拌冷卻即析出甲基哌嗪,被用于合成激素類藥物氫化潑尼松磷酸鈉。(R)-4-Boc-2-甲基哌嗪與乙酐反應(yīng)制得驅(qū)蟲藥哌硝噻唑的中間體甲酰哌嗪。制備工藝
(R)-2-甲基哌嗪(5.025g,50.2mmol)溶于DCM(100ml)中。在0℃下滴加boc酸酐(5.47g,25.1mmol)在DCM(50ml)中的溶液。將反應(yīng)混合物在室溫下攪拌1小時。過濾溶液并減壓濃縮。向殘留物中加入H2O(100ml),再次過濾。濾液用K2CO3飽和并用Et2O(3×150ml)萃取。合并的有機(jī)層在無水Na2SO4上干燥,過濾并減壓濃縮,以提供5.04g固體形式的中間體(R)-4-Boc-2-甲基哌嗪。(R)-4-Boc-2-甲基哌嗪價格(試劑級)
