Embodiment 1
[0036] 4-Benzyl-3,4-dihydro-2-phenylbenzo[f][1,4]thiazepine-5(2H)-hetero Preparation of ketone (HZkca) 1.1 Preparation of β-nitrostyrene (HZkc01)
[0037]
[0038] Dissolve 11.2g (200mmol) of KOH in 56mL of water, stir and cool in an ice-water bath; then add CH 3 NO 2 7.2g (120mmol), stirred for 5 minutes; dropwise added methanol solution (32mL) of 10.6g (100mmol) of benzaldehyde within 40 minutes; 30ml (600mmol) of concentrated hydrochloric acid was stirred for 10 minutes; the resulting solid was suction filtered and washed with water to obtain 12.2g (81.8mmol) of bright yellow needle crystals, with a yield of 81.8%.
