Procedure:
To an ethereal solution (14 ml) of lithium aluminum hydride (0.37 g) was added a solution of 1-[4-(p-fluorophenyl)-4-hydroxy-2-butynyl]-4-(p-chlorophenyl)-4-hydroxypiperidine (1.20 g) in ether (13 ml) under ice-cooling. After stirring at 10° C for 1.5 hours and further at 25° C for 4 hours, acetone was added thereto in order to consume excess of lithium aluminum hydride. The resulting mixture was poured into an aqueous ammonium chloride solution and extracted with ethyl acetate. The ethyl acetate extracts were washed with water, dried over anhydrous magnesium sulfate and concentrated to afford 1-[4-(p-fluorophenyl)-4-hydroxy-2-butenyl]-4-(p-chlorophenyl)-4-hydroxypiperidine (1.50 g) as white needles, M.P. 149° - 151° C.

Procedure:
To a solution of methyl 1-(5-bromopyridin-3-yl)cyclopropanecarboxylate (4.764 g, 18.6 mmol) in THF (190 mL) was added 90% potassium trimethylsilanolate (2.65 g, 18.6 mmol) and the reaction mixture was stirred at room temperature over night. Then, the mixture was filtered and washed with THF to give the desired product (2.668 g) as a light brown solid. The mother liquors were concentrated to around 50 mL of THF. Another portion of 90% potassium trimethylsilanolate (0.43 g) was added and stirring was continued for 5 h at room temperature. Then, the mixture was filtered and washed again with THF to give a second batch of desired product (0.953 g) which was combined with the first batch to give the title compound (3.621 g, 59.1%) as a light brown solid. MS:242.0 and 244.1 (M+H+).
