The procedure of Example 8 was followed except that a corresponding amount of 2-amino-3-(4-chloro-benzoyl)-6-benzyloxycarbonyl-4,5,6,7-tetrahydro-thieno[2,3-c]pyridine, prepared as in Example 9, was used in place of 2-amino-3-benzoyl-6-benzyloxycarbonyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine. (m.p. 164-166° C., 90% yield). 1H-NMR (CDCl3): 1.74 (m, 1 H); 1.89 (m, 2H); 2.84 (t, 2H); 3.82 (s, 2H); 6.85(sb, 2H), 7.29-7.48 (m, 5H).
