Participants

Reaction Steps

As described for example 191, 6-(5-methyl-3-phenyl-isoxazol-4-ylmethoxy)-nicotinic acid (200 mg, 0.65 mmol) was converted, using 3-amino-1-N-Boc-azetidine instead of 2-aminoethyl isopropylether, to the title compound (257 mg, 86%) which was obtained as a white solid. MS: m/e=463.3 [M−H]−.
