反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of 6.95 grams (0.025 moles) of p-bromophenacylbromide in 60 milliliters of acetone was mixed with a solution of 3.62 grams (0.025 moles) of 5-ethyl 3,4,5,6-tetrahydro-s-triazin 2(1H) thione in 500 milliliters of acetone. After 10 minutes 6-p-bromophenyl-3-ethyl-6-hydroxy-3,4,6,7-tetrahydro-2H-thiazolo(3,2-a)-s-triazine hydrobromide crystallized out as a colourless solid, m.p. 132°-134° C. The yield was 9.27 grams (88%). After 10 minutes 6-p-bromophenyl-3-ethyl-6-hydroxy-3,4,6,7-tetrahydro-2H-thiazolo(3,2-a)-s-triazine hydrobromide crystallized out as a colourless solid, m.p. 132°-134° C
