実験手順

15 ml of a 3M solution of methylmagnesium chloride in THF are added dropwise to a solution, cooled to 10° C. and under argon, of 0.7 g of methyl 6-aminonicotinate in 65 ml of THF. The reaction mixture is stirred for 15 h, while allowing the temperature to rise to 20° C., and then again cooled in an ice bath. 100 ml of a saturated ammonium chloride solution and then 200 ml of ethyl acetate are slowly added. The organic phase is dried and concentrated to dryness. The residue is taken up in ethyl acetate. The precipitate is filtered off and dried to give 0.4 g of 2-(6-aminopyridin-3-yl)-propan-2-ol in the form of a pale yellow solid.
