-
Page/Page column 20, (2009/01/24)
A method of producing a proline derivative of the following formula (1) or an acid addition salt thereof, comprising the following four steps A to D: [wherein, any two of R1, R2, R3, R4, R5 and R6 are connected to form an optionally substituted polymethylene group having 1 to 4 carbon atoms, and R7 represents an optionally substituted linear alkyl group having 1 to 10 carbon atoms, branched alkyl group having 2 to 10 carbon atoms, linear alkenyl group having 2 to 10 carbon atoms, branched alkenyl group having 3 to 10 carbon atoms or aralkyl group having 7 to 20 carbon atoms.] (Step A) A step of reacting N-protected pyrrolidinones of the following formula (2) with a reducing agent, to produce N-protected pyrrolidinols of the following formula (3): (Step B) A step of reacting the N-protected pyrrolidinols of the formula (3) obtained in the step A with a cyanodizing agent, to produce N-protected cyanopyrrolidines of the following formula (4): (Step C) A step of reacting the N-protected cyanopyrrolidines of the formula (4) obtained in the step B with alcohols and a base, to obtain imidates of the following formula (5), and treating the imidates with an acid, to produce N-protected prolines of the following formula (6): (Step D) A step of treating the N-protected prolines of the formula (6) obtained in the step C with an acid, to produce a proline derivative of the above-described formula (1) or an acid addition salt thereof.
