Procedure
According to the procedure of Example 53, Step 1, using (R)-N-benzyl-N-α-methylbenzylamine (4.2 mL, 4.24 g, 20 mmol), n-butyllithium (2.4 M, 7.4 mL), methyl 1-cyclopentene-1-carboxylate (1.3 mL, 1.29 g, 10.2 mmol), and iodoethane (1.6 mL, 3.12 g, 20 mmol), methyl (1S,2R)-2-amino-1-ethylcyclopentanecarboxylate was obtained as a mixture of two components (1.103 g) after purification on silica gel, eluting with 2% ethyl acetate/hexanes.
