Reaction Steps
To a cooled solution (5° C.) of 5-hydroxymethyl-1,3-dihydro-isoindole-2-carboxylic acid benzyl ester (11 Kg, 38.8 mol, step 7) and Et3N (7.04 L, 50.6 mol) in DCM (55 L) was added methanesulphonyl chloride (2.97 L, 38.4 mol) so that the internal temp <10° C. After stirring for 0.5 h at 5° C. the solution was used below in step 9.
