Reaction Steps

As described for example 8b, 6-(5-methyl-3-phenyl-isoxazol-4-ylmethoxy)-nicotinic acid (100 mg, 0.32 mmol) was converted, using rac-3,4-dihydro-1H-isochromen-4-amine hydrochloride instead of methylamine, to the title compound (136 mg, 96%) which was obtained as an off white solid. MS: m/e=442.3 [M+H]+.
