실험 절차
In a similar manner, 1.7 g (0.01 mole) of 1-isopropyl-3-t-butylthiourea was reacted with 2.2 g (0.01 mole) of N-chloromethyl-N-(p-fluorophenyl)-carbamoyl chloride to obtain 2-t-butylimino-3-isopropyl 5-(p-fluorophenyl)-tetrahydro-1,3,5-thiadiazin-4-one (compound No. 282): ##STR140## in the form of hydrochloride melting at 160°-195° C. Yield 2.8 g (80%). The crystals were suspended in 20 ml of water and treated in a manner similar to that described above to obtain white crystals of the free base melting at 109°-110° C. (isopropanol). Yield 2.0 g (63%).
