4-Chlorophenyl Isocyanate → HCID 15053436, compound

Participants

Reaction Steps

A mixture of 5.4 g (0.02 mole) of 3-[3-(trifluoromethyl)-phenoxy]azetidine oxalate [1:1] and 3.38 g (0.022 mole) of 4-chlorophenyl isocyanate was stirred in 20 ml of tetrahydrofuran for 15 min then treated with 5 ml of triethylamine. The reaction mixture was exothermic and was stirred for 18 hr as it cooled to ambient temperature. The reaction mixture was diluted with 100 ml of water and the residue which separated solidified. Filtration yielded 8.9 g of crude wet solid. Recrystallization from methyl isobutyl ketone and 30/60 petroleum ether yielded 3.65 g (49.7%) of fine white crystals, m.p. 138°-140° C.
