Participants

Reaction Steps

A stirred solution of 1.085 g of 35b in 10 ml of THF was treated subsequently with 1.25 ml of NEt3, 0.69 g hydroxybenzotriazole, 1.21 g of N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride and 0.63 g of 4-chloroaniline and stirring was continued at 22° C. for 16 h. The mixture was evaporated and the residue partitioned between CH2Cl2 and 1 N HCl. The separated organic layer consisting of a white suspension was filtered and the residue dried to give 1.01 g (64%) of the title compound 35c. MS: 351.4 (M+H)+.
