Procedure:
In addition to being useful as discussed above, acid anhydrides produced by the method of the invention are useful as intermediates for the production of pyrimidine diones which can be used as herbicides. For example, 3-azaisatoic anhydride can be dissolved in dimethylformamide and reacted with a substantially stoiciometric amount of isopropyl amine to produce 2-amino-N-isopropylnicotinamide. The reaction is conveniently conducted at a temperature of about 45°-50° until carbon dioxide evolution ceases. The 2-amino-N-isopropylnicotinamide can then be reacted with phosgene to produce 3-isopropyl pyrido[2,3-d]pyrimidine-2,4 (1H,3H)-dione. This reaction can be conducted under ambient pressure in p-dioxane as a solvent, preferably in the presence of triethylamine as an HCl absorber, at a temperature in the vicinity of 100°.

Procedure:
About 7 g of phosgene are passed into a solution of 10.0 g of 2,4,5-trichlorophenol in 50 ml of dichloromethane at 0° C., and the mixture is stirred at 0° C. for 15 min. 7.2 ml of quinoline in 20 ml of dichloromethane are added dropwise over the course of 30 min, and the orange-colored suspension is then stirred in an ice bath for 1 h. Subsequently nitrogen is passed through the suspension for 1 h in order to blow out excess phosgene (absorber tower). The mixture is subsequently filtered, and the filtrate is washed twice with water, dried, again filtered and evaporated to dryness in vacuo. The 4.45 g of oily brownish residue are relatively pure 2,4,5-trichlorophenyl chloroformate, which crystallizes in the refrigerator and can be employed without further purification.

A solution of 3,5-bis(trifluoromethyl)phenylacetic acid (105.3 mg, 0.387 mmol) in CH2Cl2 (5 mL) was cooled to 0° C. N,N-diisopropylethylamine (169 μL, 0.968 mmol) was added, followed by HATU (139 mg, 0.3667 mmol). The reaction was stirred at 0° C. for 2 minutes and then a solution of 1-[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methanamine (62.5 mg, 0.193 mmol) in CH2Cl2 (2 mL) was added. The reaction was stirred for 1 hour at 0° C. and then diluted with EtOAc (75 mL). The organics were washed with saturated NaHCO3 and brine (25 mL each), dried over Na2SO4, filtered, and concentrated. Purification of the residue by flash chromatography with 100% CH2Cl2 gave 2-[3,5-bis(trifluoromethyl)phenyl]-N-{[5′-isopropyl-2′-methoxy-4-(trifluoromethyl)biphenyl-2-yl]methyl}acetamide.

Procedure:
To a solution of 7-acetyl-N-(1-benzyl-1H-indazol-4-yl)imidazo[1,2-a]pyridine-3-carboxamide (Example 146; 10.8 mg, 0.026 mmol) in DCM (0.6 mL) was added morpholine (3 equivalents). The resulting solution was stirred at ambient temperature for two hours, after which sodium triacetoxyborohydride (28 mg, 0.13 mmol, 5 equivalents) was added. The resulting suspension was stirred at ambient temperature for 100 hours. The reaction was quenched with excess saturated aqueous sodium bicarbonate, and the resulting suspension was extracted with EtOAc and DCM. The combined organic extracts were dried over anhydrous sodium sulfate, and concentrated to afford the crude product. The crude product was subjected to preparative thin-layer chromatography on silica with MeOH/DCM as eluent to afford 0.3 mg of the desired product as a white solid. MS (ES+APCI) m/z=481 (M+H) detected.
