Procedure: Gaseous methylamine is passed to saturation (about 30 min) into a solution of 15.7 g of chloroethyl ethyl sulfone in 100 ml of toluene at an internal temperature of 50° C. The mixture is stirred at 50° C. for 3 h, the precipitate is filtered off with suction, and the filtrate is concentrated in a rotary evaporator. The remaining yellow mobile liquid (12.3 g) is reacted without further purification. the precipitate is filtered off with suction the filtrate is concentrated in a rotary evaporator The remaining yellow mobile liquid (12.3 g) is reacted without further purification

Conditions: temp:50.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 15.7 g of chloroethyl ethyl sulfone in 50 ml of toluene is added dropwise within 10 min to a solution of 73 g of n-butylamine and 10.1 g of triethylamine in 100 ml of toluene at an internal temperature of 50° C. The mixture is stirred at 50° C. for 5 h and allowed to cool to room temperature, the precipitate is filtered off with suction, and the filtrate is concentrated in a rotary evaporator. The remaining yellow oil (18.7 g) is reacted without further purification. to cool to room temperature the precipitate is filtered off with suction the filtrate is concentrated in a rotary evaporator The remaining yellow oil (18.7 g) is reacted without further purification

Procedure: Mix 2-chloroethyl ethyl sulfone (1.2 g, 7.66 mmol) and piperidine (2 mL, 20 mmol). Stir at room temperature for 2 hours. Treat with 5N sodium hydroxide, extract with ethyl acetate (3×50 mL) and dry (MgSO4). Concentrate in vacuo to yield 1.3 g yellow oil which crystallizes. Purify by silica gel chromatography (ethyl acetate) to yield 550 mg (35%) of the title compound as a clear oil which crystallizes; mp 45°-47° C. extract with ethyl acetate (3×50 mL) dry (MgSO4) Concentrate in vacuo
