Procedure
2-iodo-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-10-carboxylate (370.1 mg, 1.0 mmol) and Copper cyanide (268.6 mg, 3.000 mmol) were mixed in 8 ml of N,N-Dimethylformamide. The reaction was microwaved on 200 watts, 150° C., for 40 minutes. The reaction mixture was partitioned between 25 ml of 5% ammonia in water and 25 ml of EtOAc. The aqueous layer was additionally extracted with 3×20 ml EtOAc, combined extracts were washed with water, brine and dried over MgSO4 to afford 225 mg of methyl 2-cyano-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-10-carboxylate. Yield 81%. (MS: 270.0).
