実験手順

2-Amino-6-chloro-N-(5-phenoxy-thiophen-2-ylmethyl)-nicotinamide described in Example A-101 (30 mg, 0.083 mmol) was dissolved in a mixture solution of dimethylsulfoxide (1 mL) and N,N-diisopropylethylamine (0.5 mL), cyclopropylamine (0.058 mL, 0.84 mmol) was added thereto, followed by heating in a sealed tube for 15 hours 30 minutes (oil bath temperature: 130° C.). The reaction mixture was allowed to room temperature, poured into brine, which was then extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, then concentrated, the obtained residue was purified by NH silica gel column chromatography (ethyl acetate:hexane=2:1), and the title compound (15 mg, 0.039 mmol, 47.5%) was obtained.
