Abstract

A procedure for the preparation of 1,2-dialkyl (lower) pyrrolidines of formula: **(See formula)** where R1 is a group represented by the formulas: **(See formula)** where n is 2 or 3, X1 and X2 are hydrogen or lower alkyl and R2 and R3 are both lower alkyl, the process of which is characterized by dehydrating a 1,2-dialkyl (lower) -3-pyrrolidinol of the formula: **(See formula)** where R1, R2 and R3 are those defined above, to obtain compound (I).
