Reaction Steps

(R)-Ethyl 2-(1-(tert-butoxycarbonyl)pyrrolidin-3-ylamino)-6-(2-methoxyphenylamino)-5-nitropyrimidine-4-carboxylate. Ethyl 2-chloro-6-(2-methoxyphenylamino)-5-nitro-pyrimidine-4-carboxylate (See Example 30.A) (0.300 g, 0.852 mmol), (R) 1-boc-3-aminopyrrolidine (0.190 g, 1.022 mmol) and diisopropylethylamine (0.164 g, 1.27 mmol) were reacted according to General Procedure C, except at room temperature and in dimethylformamide (5 ml). The crude reaction mixture was condensed and purified using Biotage chromatography (0-100% ethyl acetate in hexanes) to afford the title compound (0.403 g, 94%). MS (ESI) m/z 503 [M+1]+.
