Procedure

To a solution of 3-{[(benzyloxy)carbonyl]amino}-N-(tert-butoxycarbonyl)alanine (10.0 g, 30.0 mmol) in DMF (100 mL) was added HATU (14.0 g, 36.0 mmol). After 2 hours, dimethylamine (4.9 g, 60 mmol) and triethylamine (15.0 g, 149 mmol) were added. After 16 hours, the reaction mixture was diluted with water and the aqueous layer was extracted with ethyl acetate (3×100 mL). The combined organic layers were dried over sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified by reverse phase HPLC (acetonitrile/water gradient) to give benzyl {2-[(tert-butoxycarbonyl)amino]-3-(dimethylamino)-3-oxopropyl}carbamate. MS ESI calc'd. for C18H28N3O5 [M+H]+ 366. found 366. 1H NMR (400 MHz, CD3OD) δ 7.33-7.31 (m, 5H), 5.31-5.20 (m, 2H), 4.61-4.48 (m, 1H), 2.93 (s, 3H), 2.87 (s, 3H), 2.74-2.71 (m, 1H), 2.71-2.68 (m, 1H), 1.43 (s, 9H).
