실험 절차

2-methoxyacetyl chloride (0.023 ml) was added in one portion to a stirred solution of 3-oxazolo[4,5-b]pyridin-2-yl-5-[1-(4-piperidyl)pyrazol-4-yl]pyridin-2-amine (90 mg) and triethylamine (0.069 ml) in THF (40 ml). The resulting mixture was stirred at 23° C. for 2 hours and concentrated to dryness. The product was purified by preparative HPLC using a Waters X-Bridge reverse-phase column (5 microns silica, 30 mm diameter, 150 mm length) and decreasingly polar mixtures of water (containing 0.2% ammonium carbonate) and acetonitrile as eluent. The fractions were evaporated to dryness and the resulting solid was triturated overnight with acetonitrile, filtered and dried under vacuum at 50° C. overnight to afford 1-[4-[4-(6-amino-5-oxazolo[4,5-b]pyridin-2-yl-3-pyridyl)pyrazol-1-yl]-1-piperidyl]-2-methoxy-ethanone (80 mg) as a solid. Mass spectrum: M+H+ 434; RT 2.23 min
