Procedure

2.01 Grams (9.127 mmoles) of N-(4-aminobutyl)tartaric acid monoamide (IX) obtained in 1. was dissolved in 40 ml of water, and after adding 1.273 ml of triethylamine and then 0.726 ml of acrylonitrile, the resulting mixture was stirred for 27 hours at room temperature. The reaction solution was then dried to solid under reduced pressure. After adding 20 ml of water to the residual solid, the resulting solution was passed through a column packed with 300 ml of Dowex® 1×4(OH-), and after washing with 1.2 liters of water, eluted with 0.5N aqueous acetic acid solution. The fractions containing the objective compound were collected and concentrated under reduced pressure to obtain 2.235 g of a syrup-form N-[4-(2-cyanoethyl)aminobutyl]tartaric acid monoamide (XI) (yield, 89.6%).
