Reaction Steps

To a suspension of 3.8 gm (100 mMol) lithium aluminum hydride in 200 mL tetrahydrofuran were added dropwise a solution of 10.0 gm (50.0 mMol) 1-methyl-cis-3,4-pyrrolidinedicarboxylic acid dimethyl ester in 50.0 mL tetrahydrofuran. The reaction mixture was stirred at ambient for about 1 hour and was then quenched by the sequential addition of 3.8 mL water, 3.8 mL 15% aqueous sodium hydroxide solution and 11.4 mL of water. The resultant mixture was stirred at ambient for 20 hours. At this point the suspension was filtered through a bed of Celite and the filter cake was washed with tetrahydrofuran. The combined liltrates were concentrated in vacuo to give 6.7 gm of the desired compound as a light yellow oil.
