Reaction Steps

Benzyl 2-[3,5-dichloro-2-methyl-6-oxo-1(6H)-pyrazinyl]acetate (400 mg, 1.22 mmol) [see preparation 17] was added to a solution of 3-(2-aminoethyl)N-(2-methoxyethyl)benzamide (260 mg, 1.25 mmol) (see preparation 41] and triethylamine (0.34 ml, 2.4 mmol) in ethyl acetate (5 ml). The reaction mixture was heated to reflux for 4 hrs, after which time the mixture was cooled to room temperature and stirred for a further 56 hrs, the mixture was partitioned between ethyl acetate (20 ml) and water (20 ml). The organic layer was washed with water (2×20 ml), brine (20 ml) and dried over MgSO4 the solvent was evaporated under reduced pressure. The crude product was purified by trituration with diethyl ether to afford the title compound, 365 mg, (60%).
