Procedure

2.62 g of (2S,4R)-4-hydroxyproline are dissolved in 15 ml of water containing 5.9 g of Na2CO3 and 5.21 g of 2-naphthalenesulphonyl chloride are added. After vigorous stirring for 18 hours at RT, the mixture is drained and the filtrate is then acidified to pH=1. The resulting mixture is again drained, washed with water and dried in order to obtain 4.1 g of the expected compound.
