Reaction Steps

Following General Procedure B: To a solution of 2,3-dihydrobenzofuran-7-carboxaldehyde (53.6 mg, 0.362 mmol) and [1-(tert-butoxycarbonyl)-(1H-benzimidazol-2-ylmethyl)]-(5,6,7,8-tetrahydro-quinolin-8-yl)-amine (136 mg, 0.361 mmol) CH2Cl2 (5 mL) was added NaBH(OAc)3 (112 mg, 0.528 mmol) and the mixture stirred overnight. Purification of the crude product by radial chromatography on silica gel (1 mm TLC plate, 125:1:1 CH2Cl2:CH3OH:NH4OH) to gave the desired freebase (48 mg, 33%).
