Cycloleucine → Methyl 1-amino-1-cyclopentanecarboxylate, HCl

Participants

Reaction Steps

1-Aminocyclopentanecarboxylic acid (1.00 g, 7.74 mmol) was added to a solution of acetyl chloride (0.60 mL, 8.44 mmol) in methanol (10 mL). The reaction mixture was allowed to stir for 18 h and then concentrated under reduced pressure. This yielded 1.35 g (97%) of the title compound. 1H NMR (400 MHz, CD3OD) δ 1.80-2.00 (m, 6H), 2.34-2.39 (m, 2H), 3.82 (s, 3H).
