Reaction Steps

The title compound was prepared in analogy to Example 92-1 in Scheme 44 by using 6-methyl-2-(1,1-dioxido-2,3-dihydro-1,4-benzothiazepin-4(5H)-yl)quinazolin-4(3H)-one (prepared in analogy to 6-methyl-2-(1-oxido-2,3-dihydro-1,4-benzothiazepin-4(5H)-yl)quinazolin-4(3H)-one in Example 91) and benzyl trans-3-amino-4-fluoropyrrolidine-1-carboxylate.
