We report here the synthesis of a series of N-aryl-2,3-dihydrobenzo[1,4]dioxine-6-sulfonamide and its N-substituted derivatives with
benzyl chloride and ethyl iodide.
Summary: Two novel 1,3,4-thiadiazole compounds, C15H10N4S2 (5a) and C18H19N3S2 (5b) were designed and synthesized by reactions of key intermediate 5-(pyridin-4-yl)-1,3,4-thiadiazole-2-thiol and two substituted
benzyl chloride (4-t-Bu and 3-CN).
chemical diversion experts, Mexico's Chemical Regulating Agency classified four chemicals as controlled precursor chemicals (nitroethane, nitromethane, benzaldehyde, and
benzyl chloride) used to manufacture methamphetamine and MDMA (ecstasy).
This observation rules out the possibility that the quaternary ammonium chloride merely acted as an in situ source of
benzyl chloride by chloride displacement of trimethylamine.
We also tested
benzyl chloride as an alkylating reagent for benzylation of A-Fmoc-protected hydrazine.
The
benzyl chloride leak occurred just before 11am at Protocol Developments Ltd, at the Merseyside Enterprise Park.
1,12-Diaminododecane, ethyl formate,
benzyl chloride, p-methoxybenzyl chloride, ally!
The departments said that by May 28, 2013 they will finalize regulations or other control instruments for
benzyl chloride, a chemical intermediate used in the manufacture of other substances.
The main derivatives of chloro toluene are
benzyl chloride, benzyl alcohol, and benzaldehyde; these are used to manufacture agricultural pesticides, pharmaceuticals, paints, dyes, and perfumes.
