Procedure

2-[2-(3,5-Difluoro-phenyl)-acetylamino]-pentanoic acid (1-piperidin-4-yl-1H-imidazol-4-yl)-amide (100 mg, 2.4 mmol) was charged with 1 mL of THF, 1 mL of Dichloroethane, 0.06 mL of triethyamine, 0.03 mL of 3,3-dimethylbutyraldehyde, and 63 mg of sodiumtriacetoxyborohydride. The reaction was stirred overnight, quenched with sodiumbicarbonate, extracted with methylene chloride, and the resultant oil purified by silica gel chromatography to afford the title compound: C13 NMR (100 MHz, CDCl3) 13.9, 18.8, 29.7, 29.9, 33.3, 36.0, 40.9, 43.1, 52.9, 53.1, 54.5, 55.9, 102.8, 103.1, 105.9, 112.3, 112.4, 112.5, 112.6, 131.5, 137.6, 169.2; MS 504.3 m/z (M+1).
