      Abstract:

      ClCH2(C(OEt)3 (I) was prepd. by chlorination of CH3C(OEt)3 with   N-chlorosuccinimide.  I underwent cyclocondensation   reactions with aminophenols or -thiophenols to afford   benzoxazoles or benzothiazoles II (X = O, S; Rn = H, 5-Br, 5- or   6-CF3, 5,7-F2, etc.).  I and 3-amino-2-mercaptopyridine or   2-amino-3-hydroxypyridine gave   2-chloromethylthiazolo[5,4-b]pyridine or -oxazolo[4,5-b]pyridine,   resp.
