反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 2'-Acetylmethanesulfonanilide (1.0 g, 4.7 mmol) in 10 ml tetrahydrofuran is reacted with 0.23 g (4.8 mmol) of 50% sodium hydride dispersion in mineral oil at 5° C. for 15 min. Methyl iodide (1.5 g, 10.56 mmol) in 10 ml of dimethylformamide is added over 15 min at 0°-10° C. and stirred in cold for 15 min. Dimethylformamide (10 ml) is added, and the reaction is stirred for 2 days at room temperature. The reaction is taken up into ethyl acetate, the organic layer washed with water, sodium carbonate solution, water, and saturated sodium chloride successively. The dried organic layer is evaporated and the product crystallized from ether-pet. ether; m.p. 98°-99° C. the reaction is stirred for 2 days at room temperature the organic layer washed with water, sodium carbonate solution, water, and saturated sodium chloride successively The dried organic layer is evaporated the product crystallized from ether-pet. ether

实验步骤: 2'-(Bromoacetyl)methanesulfonanilide can be derived from 2'-acetylmethanesulfonanilide (Preparation 1) following the bromination procedure described in Example 10, Step X. In a like manner, 3'-(2-bromoacetyl)methanesulfonanilide can be obtained.
