preparation example IV
[0128] Preparation IV: 4-((±)trans-3,4,4a,10b-tetrahydro-9-methoxy-2H,5H-[1]-benzopyran-[4,3-b] And-1,4-oxazin-yl)butyl-1-amine (70-1) and 4-((±)cis-3,4,4a,10b-tetrahydro-9-methoxy-2H , 5H-[1]-benzopyran-[4,3-b]-1,4-oxazin-yl)butyl-1-amine (71-1)
[0129]
[0130] Replace phenol (53) with p-methoxyphenol (53-1), and operate with the above-mentioned sequential experimental steps to prepare 4-((±)trans-3,4,4a,10b-tetrahydro-9-methoxy -2H, 5H-[1]-benzopyran-[4,3-b]-1,4-oxazin-yl)butyl-1-amine (70-1) and 4-((±) cis-3,4,4a,10b-tetrahydro-9-methoxy-2H,5H-[1]-benzopyran-[4,3-b]o-1,4-oxazin-yl ) Butyl-1-amine (71-1).
[0131] Preparation IV: 4-((±)trans-3,4,4a,10b-tetrahydro-2H,5H-[1]-benzothiopyran-[4,3-b]a-1, 4-oxazin-yl)butyl-1-amine (70-2) and 4-((±)cis-3,4,4a,10b-tetrahydro-2H,5H-[1]-benzothio Substituted pyran-[4,3-b]-1,4-oxazin-yl)butyl-1-amine (71-2)
[0132]Using thiophenol (53-2) instead of phenol (53), follow the above-mentioned sequential experimental steps to pre...
Embodiment 1
[0133] Example 1: N-[4-((±)trans-3,4,4a,10b-tetrahydro-2H,5H-[1]-benzopyran-[4,3-b]-1 , 4-oxazin-yl) butyl]-1-naphthylcarboxamide (I a-4)
[0134]
[0135] Get compound (70) 0.52g to dissolve with 20ml chloroform, add K 2 CO 3 2g and 2g of naphthoyl chloride were dissolved in an appropriate amount of chloroform, added dropwise with a constant pressure dropping funnel, after the dropwise addition, suction filtered, the mother liquor was concentrated under reduced pressure, and separated by column chromatography to obtain 0.67g of a white solid, with a yield of 82.3% , mp161-162°C.
