Reaction Steps
A suspension of 1.600 g (5.0 mmoles) of Z-(L)-Pro-(L)-AlaOH (Sigma) in 80 ml of dry methylene chloride (CH2Cl2) was brought in an argon atmosphere to a temperature of approximately -20° C. On stabilization of the temperature, the following were added in quick succession: 0.670 ml (5.13 mmoles) of isobutylchloroformate (IBCF) and 0.570 ml (5.17 mmoles) of 4-methylmorpholine (NMM), leaving the system under stirring for approximately 2 minutes.
