Reaction Steps

2-(4-Methoxy-4-oxobutanamido)nicotinic acid (ii-h-1) (1.28 g, 4.8 mmol) was dissolved in an equimolar mixture of CH2Cl2 and methanol (20 mL) and cooled to 0° C. TMS diazomethane (2M solution in diethyl ether; 5.2 mL, 10.6 mmol) was added dropwise. The mixture was stirred for 1 h and warmed to 23° C. Volatiles were removed under reduced pressure to provide ii-h as a pale yellow solid (1.37 g, 100%) MS m/z═267 (M+1).
