Methyl-5-phenyl-3,6-dihydro-27/-l,3,4-thiadiazin-2-imine (164) is available in excellent yield by de-r-butylation of the 2-(t-butylamino)-derivative (163) with 48% HBr <90EGP280760>. Deallyl-ation is achieved in a similar manner. Curiously, in both instances, ring contraction to a pyrazole (Section 6.17.5.2) does not appear to occur.
