Diethyl Ether → HCID 10303191, compound

Participants

Reaction Steps

A stirred suspension of benzyl-3,3,3-trifluoropropyl-amine hydrochloride (152.8 mg, 3 equiv.) in methylene chloride (10 mL) at room temperature was treated with diisopropylethylamine (0.132 mL, 3 equiv.). Within a few minutes the mixture became homogeneous and then a 12.5 mg/mL solution of (5-chloromethyl-4-trifluoromethyl-thiazol-2-yl)-(2,4,6-trichloro-phenyl)-amine in ether (8 mL, 0.2525 mmoles) was added all at once. After 12 hours at room temperature, the mixture was evaporated and the residue partitioned between ethyl acetate and water. The organic phase was washed with brine, dried over sodium sulfate and evaporated. The residue was chromatographed on silica gel, eluting with 12% ethyl acetate/hexane, to give the product as a colorless glass (133.6 mg, 94%). 1H-NMR δ (CDCl3) 2.27 (m, 2H), 2.75 (ABq, 2H), 3.62 (s, 2H), 3.74 (s, 2H), 7.28 (m, 5H), 7.48 (s, 2H), 8.75 (br, 1H). Mass spec.: 563.98 (MH+).
