実験手順

2-Cyano-5-nitro-3-trifluoromethylpyridine (0.065g, 0.3 mmol) was reacted in the same manner as described in example 762D to give the desired compound 763E (0.046g, 82%) as a gold colored solid after trituration with ether. HPLC: 100% at 2.07 min(YMC S5 ODS column) eluting with 10–90% aqueous methanol containing 0.2% phosphoric acid over a 4 min gradient monitoring at 220 nm. MS (ES): m/z 187.82 [M+H]+.
