83% | at 0 - 20℃; for 3 h; | To a solution of tert-butyl 5-formyl-1H-indo . g, 12.23 mmol) in methanol (30 mL) was added sodium tetrahydroborate (0.463 g, 12.23 mmol) at 0 °C. The reaction mixture was stirred at 0 °C for 3 hours then overnight at room temperature. The resulting solution was diluted with water (40 mL), then extracted with ethyl acetate (3 x 30 mL). The organic layers were combined, washed with aqueous sodium carbonate and brine, dried and concentrated under vacuum to afford tert-butyl 5-(hydroxymethyl)-1H-indole-1- carboxylate (2.5 g, 10.11 mmol, 83percent yield) as a yellow oil. LCMS m/z = 270.3 [M+Na]+. |

11% | With sodium tris(acetoxy)borohydride In 1,2-dichloro-ethane at 20℃; for 8 h; | D-Leucinamide (1.0 g, 6.0 mmol), 1-(t-butyloxycarbonyl)-5-formylindole (Example 1, 1.23 g, 5.0 mmol) and DCE (15 mL) were mixed at room temperature. Sodium triacetoxyborohydride (1.48 g, 7.0 mmol) was added in one portion with vigorous stirring. After 2 h, another portion (0.15 g, 0.7 mmol) was added and stirring was continued for an additional 6 h. The reaction mixture was diluted with a saturated NaHCO3 solution (10 mL). Three extractions with EtOAc, washing the combined organic layers with brine, drying over Na2SO4 and filtration provided a solution. Removal of solvent in vacuo afforded an oil. Column chromatography (DCM:MeOH:95:5) provided three fractions, after removal of solvent in vacuo: (1) 1-(t-Butyloxycarbonyl)-5-hydroxymethylindole (162 mg, 11percent yield, Rf=0.5): 1H NMR (CDCl3, 300 MHz): 8.11 (d, 1H, J=8), 7.61 (d, 1H, J=2), 7.54 (s, 1H), 7.31 (dd, 1H, J=8,2), 6.55 (d, 1H, J=3), 4.75 (s, 2H), 1.69 (s, 9H); (2) 2R-bis-(1-t-butyloxycarbonylindol-5-ylmethyl)amino-4-methylpentanamide BMS594447 (382 mg, 12percent yield, Rf=0.4): 1H NMR (CDCl3, 300 MHz): 8.1 (d, 2H, J=8), 7.61 (d, 2H, J=2), 7.52 (s, 2H), 7.31 (dd, 2H, J=8,2), 6.62 (m, 1H), 6.56 (d, 2H, J=4), 6.05 (br s, 1H), 3.85 (d, 2H, J=16), 3.66 (d, 2H, J=16), 3.35 (m, 1H), 1.69 (s, 18H), 0.96 (d, 3H, J=7), 0.87 (d, 3H, J=7); MS (ES+): 589.4 (C35H45N3O5) and (3) the title product (986 mg, 55percent yield, Rf=0.3): 1H NMR (CDCl3, 300 MHz): 8.10 (d, 1H, J=8), 7.61 (d, 1H, J=2), 7.49 (d, 1H, J=1), 7.28-7.20 (m, 3H), 6.55 (d, 1H, J=4), 3.93 (d, 1H, J=16), 3.77 (d, 1H, J=16), 3.28-3.20 (m, 1H), 1.69 (s, 9H), 0.94 (d, 3H, J=7), 0.85 (d, 3H, J=7); MS (ES+): 360 (C20H30N3O3, M++H). |
