실험 절차

1-(Benzo[d][1,3]dioxol-5-yl)-N-(5-(2-methoxybenzoyl)pyridin-2-yl)cyclopropanecarboxamide (0.50 g, 1.2 mmol) was suspended in 25 mL of methanol. Sodium borohydride (0.454 g, 12.0 mmol) was added in small portions. After stirring for one hour the reaction mixture was evaporated to dryness and purified on 40 g of silica gel utilizing a gradient of 15-70% ethyl acetate in hexanes to yield the pure product as a white solid (0.2125 g, 0.5078 mmol, 42%). ESI-MS m/z calc. 418.6. found 419.3 (M+1)+. Retention time 2.59 minutes.
