To a stirred solution of 4-chloro-2,6-diisopropylaniline (32 grams) and triethylamine-(7.8 mL) in tetrahydrofuran (505 mL) was added triphosgene (14.9 grams). The mixture was refluxed for two hours with stirring. The tetrahydrofuran was then revolved in vacuo and the resulting oil was taken up in pentane and filtered through silica gel to afford 33.3 grams of the product. 1H NMR δ 7.18 (s, 2), 3.22 (qq, 2, J=7.1Hz), 1.25 (d, 6, J=7.1Hz), 1.25 (d, 6, J=7.1 Hz).
