4-N-methylpiperazinyl-2-methoxycarbonylfuro[2,3-b][1,5]benzothiazepine 4a was obtained by the Bischler-Napieralski reaction of 3a with phosphorus oxychloride in the present of phosphorus pentoxide. Three furobenzothiazepines could be obtained using the same method. Based on the pharmacological studies of these compounds, it was found that 4-morpholinyl-2-methoxycarbonylfuro[2,3-b][1,5]benzothiazepine 4b had anti-inflammatory
5-(2-异氰酸根合苯硫基)-2-呋喃甲酸甲酯2与N-甲基哌嗪的反应得到5-(2- N-哌嗪基氨基甲酰基苯硫基)-2-呋喃甲酸3a。此外,4- Ñ -methylpiperazinyl -2- methoxycarbonylfuro [2,3- b ] [1,5]苯并硫氮杂4A通过的比施勒-纳皮耶拉尔斯基反应得到3a中与磷酰氯在本五氧化二磷。用相同的方法可以得到三种呋喃苯并硫氮杂s。基于这些化合物的药理研究,发现4-吗啉基-2-甲氧基羰基呋喃[2,3- b ] [1,5]苯并噻氮平4b 具有类似于氟芬那酸的抗炎活性。
