Potassium Carbonate → HCID 15053402, compound

Participants

Reaction Steps

A stirred mixture of 2.8 g (0.01 mole) of 3-[3-(trifluoromethyl)phenoxy]-1-azetidinecarbonyl chloride and 1.4 g (0.01 mole) of potassium carbonate in 25 ml of tetrahydrofuran was treated with 2 g (0.01 mole) of 4-(4-chlorophenyl)-4-hydroxypiperidine added in small portions. After stirring for 30 min, a few pieces of ice were added and stirring continued for 16 hr. The reaction mixture was diluted with 200 ml of water and the oil which separated was extracted into methylene chloride (2×50 ml). The combined extracts were dried over magnesium sulfate and concentrated in vacuo to give a water-like oil (5.16 g). A crystalline solid was obtained by cooling to -78° C. and recrystallization was accomplished by dissolving the residue in 5 ml of acetone and 75 ml of isopropyl ether and reducing the volume under nitrogen to 40 ml. Upon cooling, filtration yielded 3.6 g (79.1%) of fine white crystals, m.p. 127°-128.5° C.
