Procedure

Oxalyl chloride in methylene chloride (2.00 M, 3.0 mL) was added to a suspension of 2-(1-(2-chlorophenyl)-1H-1,2,4-triazol-5-yl)-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-10-carboxylic acid (112 mg, 0.178 mmol) in 30 ml of methylene chloride. Catalytic amount of N,N-Dimethylformamide (1.0 uL, 0.013 mmol) was added and the mixture was stirred for 2 hours. The mixture was filtered, the filtrate was concentrated in vacuum and the residue dried in high vacuum for 1 hour. The above residue was dissolved in N,N-dimethylacetamide (3.0 mL, 32 mmol) and saturated with gaseous ammonia. The mixture was stirred for 20 min, concentrated in vacuum, dissolved in aqueous methanol and subjected to RP HPLC purification to yield 18.5 mg of 102 (26%), MS: 407.1. 1H NMR (400 MHz, DMSO) δ 8.26 (d, J=2.2, 1H), 8.20 (s, 1H), 7.80 (s, 1H), 7.72-7.51 (m, 6H), 7.29 (s, 1H), 7.00 (d, J=8.5, 1H).
