Procedure

N-[5-tert-Butyl-2-methoxy-3-(piperidine-1-carbonyl)-phenyl]-2-[4-(2-morpholin-4-yl-ethoxy)-naphthalen-1-yl]-2-oxo-acetamide (31) 26 mg (0.049 mmol) of the compound obtained above was converted to the acid chloride by reaction with oxalyl chloride (54 μl, 0.5 mmol) in 0.5 mL DCM in the presence of a catalytic amount of DMF (rt, 2h). After removal of the solvent, the crude acid chloride was dissolved in 1 mL DCM. DIEA (0.2 mmol) was added, followed by the addition of piperidine (0.1 mmol). The resulting mixture was stirred at rt overnight. Aqueous work-up and purification by LC-MS resulted in 7.6 mg pure product. Calculated mass=602. Observed mass=602
