Yield	Reaction Conditions	Operation in experiment
	With triethylamine; In tetrahydrofuran; at 0 - 23℃; for 1.67h;	To a solution of 1 -methyl-2-piperidine-methanol (Aldrich, 0.27 mL, 2.1 mmol) in 10 mL tetrahydrofuran (THF) at 0 0C was added triethylamine (0.87 mL, 6.22 mmol) followed EPO <DP n="34"/>by methanesulfonyl chloride (0.24 mL, 3.1 mmol). The mixture was stirred at 0 0C for 10 min then the ice-bath was removed and the reaction mixture was stirred at 23 0C for an additional 1.5 h. The reaction mixture was filtered though Celite with THF and concentrated under reduced pressure. This crude material was used directly in the next reaction.

Yield	Reaction Conditions	Operation in experiment
	With LiAlH4; In tetrahydrofuran;	EXAMPLE 10 1-Methyl-2-piperidinemethanol The title compound of Example 9 (23.2 g, 101 mmol) in dry THF (100 mL) was added dropwise to a 1.0M solution of LiAlH4 in THF (405 mL, 405 mmol, 4eq) and the reaction mixture was refluxed overnight and the product was isolated as described in Example 6 to give the product (13.1 g, quantative) as a colorless oil. The fumarate salt crystallized from 2-propanol: mp 118°-120° C.; 1 H-NMR (CDCl3) dd;3.85 (dd, J=gem=11 Hz, J=3.9 Hz, 1H), 3,39 (dd, J=gem=11 Hz, J=2.2 Hz, 1H), 2.89 (m, 1H), 2.30 (s, 3H), 2.15 (m, 1H), 1.97 (m, 1H), 1.76 (m, 1H), 1.42-1.68 (complex m, 4H), 1.28 (m, 1H); CIMS (MH+ calcd for C7 H15 NO): 130.
