1-(Bromomethyl)-2,4,5-trichlorobenzene → 4,6-Diamino-1,2-dihydro-1-(2,4,5-trichlorophenylmethoxy)-2,2-dimethyl-1,3,5-triazine hydrobromide

Participants

Reaction Steps

A solution of 0.6 gram (0.004 mole) of 4,6-diamino-1,2-dihydro-1-hydroxy-2,2-dimethyl-1,3,5-triazine and 1.6 grams (0.006 mole) of 2,4,5-trichlorophenylmethyl bromide in 5 ml of dimethylformamide was stirred in a closed reaction vessel during about an 18 hour period. After this time the reaction mixture was concentrated under reduced pressure to a residual solid. The solid was washed with 50 ml of acetone. The dried solid was recrystallized from 125 ml of water, yielding 1.1 grams of 4,6-diamino-1,2-dihydro-1-(2,4,5-trichlorophenylmethoxy)-2,2-dimethyl-1,3,5-triazine hydrobromide, m.p. 247°-248° C. The NMR spectrum was consistent with the proposed structure.
