PROCEDURE

实验过程

(2-Amino-6-formyl-3-nitro-pyridin-4-yl)-(6-methyl-pyridin-3-ylmethyl)-carbamic acid ethyl ester (190 mgs/0.529 mmols) was dissolved in MeOH (5 mls). Added (4-tolylsulphonyl)methylisocyanide (124 mgs/0.634 mmols) followed by anhydrous potassium carbonate (200 mgs/1.45 mmols). Stirred under N2 for 1 hr then concentrated in vacuo. Partitioned between EtOAc (100 mls) and H2O (50 mls). Organic collected, washed with brine, dried over Na2SO4, filtered and concentrated to a black resin. Purification by column chromatography eluting with 90:10 DCM/MeOH gave the title compound (135 mgs) as a crude brown solid.
