Procedure
Isobutyl chloroformate (520 μL, 4.0 mmol) was added to a solution of N-Boc leucine monohydrate (1.0 g, 4.0 mmol) and N-methyl morpholine (440 μL, 1.73 mmol) in THF at 0° C. After two minutes, 3-methoxypropylamine (410 μL, 4.0 mmol) was added and the mixture was allowed to warm to rt. After thirty minutes, the reaction mixture was filtered through a bed of celite and all volatiles were removed under reduced pressure to yield N-Boc-L-leucine-3-methoxypropyl amide (1.10 g, 92%) as a white solid. 1H NMR: (CDCl3) δ 0.93, 6H, d; 1.42, 9H, s; 3.35, 3H, s; 3.38, 2H, d; 3.43 m 2H, t; 4.03m 1H, m; 4.39, s, 1H; 4.91, 1H, m; 6.60, 1H, m,
