4-Bromophenacyl bromide → HCID 86736178, compound

Participants

Reaction Steps

A solution of 6.95 grams (0.025 mole) of p-bromophenacyl bromide in 60 milliliters of acetone was mixed with a solution of 3.93 grams (0.025 mole) 5-allyl-3,4,5,6-tetrahydro-s-triazin-2(1H)-thione in 1100 milliliters of acetone and the mixture was left for 1 hour at room temperature. The solution was then concentrated to 200 milliliters. 10.1 Grams (89% yield) of 3-allyl-6-(p-bromophenyl)-6-hydroxy-3,4,6,7-tetrahydro-2H-thiazolo[3,2-a]-s-triazine hydrobromide 1/3 acetonate crystallised as a colourless solid of melting point 146°-148° C. (with decomposition).
