Procedure

A mixture of 2-(4-chloro-2,6-dimethyl-phenoxy)-4-(1-hydroxymethyl-propylamino)-6-methyl-nicotinic acid methyl ester (106 mg, 0.27 mmol), triphosgene )27 mg, 0.090 mmol), triethylamine (27 mg, 0.27 mmol) in dry THF was stirred at room temperature for 2 hr. The mixture was quenched with water and extracted with ethyl acetate. The organic layer was separated, washed with water, dried over anhydrous sodium sulfate, filtered, arid concentrated to dryness to give 13.6 g of crude product as a white glass foam. The foam was triturated with hexane/diethyl ether to give a white solid, mp. 144-145.5° C., Anal. For C21H23ClN2O5 calc.: C, 60.22; H, 5.53; N, 6.69; found: C, 60.10, H, 5.79; N, 6.66.
