The reaction was repeated on the same scale under the same conditions and the two crude reaction mixtures were then combined for work up and purification. The reaction mixture was evaporated in vacuo to yield a pale yellow solid. This solid was partitioned between water (~30 ml) and DCM (~50 ml). The layers were separated and the aqueous was re-extracted with DCM (2 x -50ml). The organic layers were combined, washed with water (~30 ml) and brine (-3 0 ml) then evaporated to a solid. This solid was triturated with ether then filtered to yield the product as an off white solid (129 mg, 62%). 1H NMR: 1.35 (s, 9H), 2.40 (m, 2H), 2.70 (m, 1 H), 2.90 (br m, 2H), 3 .10 (m, 1H), 3.20 (d, 2H), 3.35 (s, 2H), 4.00 (br m, 1H), 4.10 (m, 1H), 4.60 (m, 1H), 6.75 (t, 1H), 7.05 (m, 1H), 7.10 (t, 2H), 7.25 (m, 2H), 7.65 (br d, 1H), 8.20 (d, 1H), 8.25 (m, 1H); MS: 465 (M+Na)+.

YieldReaction ConditionsOperation in experiment
With 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; triethylamine; In acetonitrile; at 100.0℃; for 0.2h;Microwave irradiation; Example 6: (R)-3-Amino-4-(4-fluorophenyl)-N-(2-oxo-1,2,3,4-tetrah-vdro-1,7- nauhthyridin-3-yl) butanamide; In a microwave tube was placed 3-amino-3,4-dihydro-1H 1,7-naphthyridin-2-one dihydrochloride (Intermediate 9, 63 mg, 0.27 mmol), (R)-3-tert-butoxycarbonylamino-4-( 4- fluorophenyl) butanoic acid (80 mg, 0.27 mmol), triethylamine (79 mul, 0.56 mmol), HOBT (40 mg, 0.30 mmol) and EDAC (52 mg, 0.27 mmol) in acetonitrile (5 ml). The reaction was heated by microwave to 100C for 12 minutes. The reaction was repeated on the same scale under the same conditions and the two crude reaction mixtures were then combined for work up and purification. The reaction mixture was evaporated in vacuo to yield a pale yellow solid. This solid was triturated with water then filtered and dried under high vacuum to yield the crude Boc-protected compound. This compound was suspended in dioxan (5 ml) and treated with 4M HCI in dioxan (15 ml). The resulting reaction was stirred over night at ambient temperature. The volatiles were removed under reduced pressure and the resulting residue was partitioned between 1M NaOH solution (-2 ml) and DCM (~30 ml). The layers were separated and the aqueous was re-extracted with DCM (2 x -40 ml). The combined organic layers were evaporated to yield a residue. This residue was loaded onto a l Og SCX-2 column and eluted with MeOH ((at)100 ml). The product was then eluted off using 1% ammonia in methanol. The fractions containing product were combined and evaporated to yield the product as the free base (121 mg, 66%). 1H NMR: 2.10 (m, 1H), 2.20 (m, 1H), 2.55 (m, 1H), 2.65 (m, 1H), 3.00 (t, 1H), 3.10 (m, 1H), 3.10-3.30 (br m, 3H), 4.50 (m, 1H), 7.10 (t, 2H), 7.25 (m, 3H), 8.10 (m, 2H), 8.40 (m, 1H); MS: 343 (M+H)+.
