90% | Step 1. Synthesis of [(R)-Cyclohexyl-(methoxy-methyl-carbamoyl)-methyl]-carbamic acid benzyl ester To a solution of (R)-benzyloxycarbonylamino-cyclohexyl-acetic acid (25 g, 88 mmol) in DMF (100 mL) at -10 C was added HATU (36.7 g, 96 mmol, 1 .0 equiv) followed by Nu,Omicron- dimethyl hydroxyamine HCI salt (10.3 g, 105 mmol, 1 .2 equiv). To this solution was then slowly added N-methyl morpholine (28.9 mL, 263 mmol, 3.0 equiv). The internal temperature was carefully monitored. During the addition, the internal temperature rose to 0 C. The solution was stirred at 0 C for 2 hours after which the solution was diluted with EtOAc (500 mL) and washed with sat. aq. NaHC03 solution, water, 1 .0 N aq. HCI solution and brine. The organic layer was dried over Na2S04 and the solvent including DMF was removed under vacuum. The residue was diluted with EtOAc and the solution was washed with water, brine, dried (MgS04) and concentrated to give product [(R)-Cyclohexyl-(methoxy-methyl-carbamoyl)-methyl]- carbamic acid benzyl ester 26 g (yield 90 %). |

59% | With N-ethyl-N,N-diisopropylamine; N-[(dimethylamino)-3-oxo-1H-1,2,3-triazolo[4,5-b]pyridin-1-yl-methylene]-N-methylmethanaminium hexafluorophosphate; In N,N-dimethyl-formamide; at 40℃;Inert atmosphere; Sealed tube; | General procedure: In a typical run, a 15 mL screw cap tube was charged with the selected carboxylic acid (0.5 mmol), HATU (2 equiv/mol), DMF(1 ml) and DIPEA (2 equiv/mol.). A solution of 1 or 2 (0.5 mmol) in DMF (1 ml) was then added dropwise. The tube was flushed with argon, sealed, and the mixture was stirred overnight at 40 C. After cooling down to rt, the crude reaction mixture was diluted with water (10 mL) and extracted with EtOAc(3 15 mL). The combined organic layers were washed with brine(3 15 mL), dried over anhydrous MgSO4, filtered and concentrated under reduced pressure to give a residue, which was purified as indicated for each compound (see Supporting material). |

92% | With N-ethyl-N,N-diisopropylamine; HATU; In N,N-dimethyl-formamide; for 18h; | To a solution of 91B (0.125 g, 0.332 mmol, 1.0 eq.) in DMF (1 mL) were added Z-Chg-OH (0.106 g, 0.364 mmol, 1.1 eq.), DIPEA (0.17 mL, 0.996 mmol, 3.0 eq.) and HATU (0.189 g, 0.498 mmol, 1.5 eq.) and the resulting mixture was stirred for 18 h. Aqueous saturated sodium bicarbonate solution was added and then extracted with EtOAc. The combined organic phase was washed with brine, dried over sodium sulfate then concentrated to dryness to afford 92B as an orange solid (0.199 g, 92%) which was used in the next step without further purification.

94% | To a solution of Z-Chg-OH 4 (0.816 g, 2.80 mmol, 1.2 eq.) in DMF (12.0 mL) was added HATU (1.34 g, 3.51 mmol, 1.5 eq.) and DIPEA (1.22 mL, 7.02 mmol, 3.0 eq) and then stirred at RT for 10 min. A solution of 3 (0.585 g, 2.34 mmol, 1.0 eq,) in DMF (10.0 mL) was added and the resulting mixture was stirred at RT for 1 h. The mixture was concentrated to dryness and the residue triturated with EtOAc/heptane (9:1) to afford 5 as a white solid (1.10 g, 94%). 1H NMR (400 MHz, DMSO-d6) δ 10.01 (s, 1H), 8.78-8.09 (m, 2H), 7.55-7.27 (m, 8H), 7.13 (d, J=8.1 Hz, 2H), 5.03 (s, 2H), 4.43 (td, J=8.6, 5.6 Hz, 1H), 4.00 (t, J=8.3 Hz, 1H), 3.61 (s, 3H), 3.16-3.07 (m, 1H), 2.96 (dd, J=13.8, 5.6 Hz, 1H), 2.83 (dd, J=13.8, 9.2 Hz, 1H), 2.07 (q, J=7.6 Hz, 2H), 1.76-1.51 (m, 4H), 1.17-0.99 (m, 5H), 0.92 (t, J=7.6 Hz, 3H).
