2-Methyl-2-(2'-methoxyethylsulfonamido)propionitrile

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

Procedure: To a stirred mixture of 10 g (0.12 mole) 2-amino-2-methyl-propionitrile and 12.1 g (0.12 mole) triethylamine in about 200 ml methylene chloride cooled by an ice bath, 18.8 g (0.12 moles) 2-methoxyethane sulfonyl chloride (the product of Example 19) in 15 ml methylene chloride were added dropwise. The reaction mixture was then stirred at room temperature over the weekend. The reaction mixture was washed three times with equal amounts (about 200 ml) water, dried over magnesium sulfate, filtered and stripped to give an oil. The oil was recrystallized from ethyl ether/petroleum ether to give 15.0 g of the above-identified product, melting point 58°-60° C. cooled by an ice bath The reaction mixture was washed three times with equal amounts (about 200 ml) water dried over magnesium sulfate filtered to give an oil The oil was recrystallized from ethyl ether/petroleum ether
