Известны лишь производные пиримидо [i2,5-&] ['1,5]тиазепинона, способ получени которых основан на реакции 5-амино-6-меркапто- пиримидинов с хлорангидридом р-бромпропио- новой кислоты с последующей циклизацией образующихс при этом 5-(р-бромпропионил) амино-6-меркаптопиримидинов и пиримидоти- азепины.Оказалось, что этим методом нельз получить пиридотиазепиноны, так как реакци 2-меркапто-З-аминопиридинов с хлорангидридом р-бромн|ропионовой кислоты протекает одновременно по амино- и меркаптогруппе, в результате чего образуютс соединени , от которых не удаетс перейти к пиридотиазепино- нам.Предлагаетс способ получени ииридо [2,3-6] [1,5]тиазепинонов общей формулы 1Ri , , I ^',N—<где R — водород, алкоксил или галоид;RI — водород или алкил.
