6-methyl-1,4-oxazepane;hydrochloride

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a slurry of 2-chloro-1-methyl-1H-[4,4′]bipyrimidinyl-6-one (113 mg, 0.507 mmol) and 6-methyl-[1,4]oxazepane hydrochloride (100 mg, 0.660 mmol) in tetrahydrofuran (1.1 mL) was added triethylamine (154 mg, 1.52 mmol) at room temperature. The mixture was stirred for 15 hours and partitioned between water and ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate and concentrated in vacuo. The crude product was washed with ether and dried under reduced pressure to afford 1-methyl-2-(6-methyl-[1,4]oxazepan-4-yl)-1H-[4,4′]bipyrimidinyl-6-one (A087) as white solid (92.2 mg, 60%). partitioned between water and ethyl acetate The organic layer was washed with brine dried over sodium sulfate concentrated in vacuo The crude product was washed with ether dried under reduced pressure

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of 4-(4-methoxy-benzyl)-6-methyl-[1,4]oxazepane (3.24 g, 13.8 mmol) in 1,2-dichloroethane (23 ml) was added 1-chloroethyl chloroformate (4.93 g, 34.5 mmol) at room temperature. The mixture was refluxed for 7 hours. The reaction mixture was cooled to room temperature and then methanol (30 ml) was added. The mixture was refluxed for 5 hours and concentrated in vacuo. This crude product was washed with hexane, dried under reduced pressure to afford 6-methyl-[1,4]oxazepane hydrochloride as white solid (1.73 g, 83%). The mixture was refluxed for 7 hours The mixture was refluxed for 5 hours concentrated in vacuo This crude product was washed with hexane dried under reduced pressure

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
