specific Embodiment approach
[0258] The technical solutions of the present invention will be further described below in conjunction with specific examples, but the protection scope of the present invention is not limited to these examples. All changes or equivalent substitutions that do not depart from the concept of the present invention are included in the protection scope of the present invention.
[0259] The experimental methods for which specific conditions are not indicated in the following examples are usually in accordance with the conventional conditions of this type of reaction, or in accordance with the conditions suggested by the manufacturer. Percentages and parts are by weight unless otherwise indicated. Unless otherwise stated, ratios of liquids are by volume.
[0260] The experimental materials and reagents used in the following examples can be obtained from commercial sources, prepared according to methods in the prior art or prepared according to methods similar to those disclosed in t...
Embodiment 1
[0277] Example 1: 2-acetyl-6-(ethylsulfonyl)-N-(4-(1,1,1,3,3,3-hexafluoro-2-hydroxypropan-2-yl)phenyl )-1,2,3,4-tetrahydroisoquinoline-1-carboxamide
[0278]
[0279] Step 1: Synthesis of 3-(2-aminoethyl)phenol hydrobromide
[0280]
[0281] 2-(3-Methoxyphenyl)ethanamine (9.00 g, 59.5 mmol) was dissolved in 40% aqueous hydrobromic acid (120 g, 595 mmol). The reaction solution was stirred and reacted at 110°C for 6 hours, and the reaction was complete as monitored by LC-MS. The reaction solution was concentrated under reduced pressure to obtain the target compound (9.00 g, crude product, light brown solid). LC-MS(ESI)m / z:179.1[M+ACN+H] + .
[0282] Step 2: Synthesis of ethyl 6-hydroxy-1,2,3,4-tetrahydroisoquinoline-1-carboxylate hydrobromide
[0283]
[0284] 3-(2-Aminoethyl)phenol hydrobromide (9.00 g, 65.6 mmol) was dissolved in ethanol (90 mL). At room temperature, 50% ethyl glyoxylate toluene solution (14.7 g, 72.2 mmol) was added dropwise to the reaction sol...
Embodiment 2 and 3
[0309] Examples 2 and 3: (R)-2-Acetyl-6-(ethylsulfonyl)-N-(4-(1,1,1,3,3,3-hexafluoro-2-hydroxypropane- 2-yl)phenyl)-1,2,3,4-tetrahydroisoquinoline-1-carboxamide or (S)-2-acetyl-6-(ethylsulfonyl)-N-(4- (1,1,1,3,3,3-Hexafluoro-2-hydroxypropan-2-yl)phenyl)-1,2,3,4-tetrahydroisoquinoline-1-carboxamide
[0310]
[0311] Racemate 2-acetyl-6-(ethylsulfonyl)-N-(4-(1,1,1,3,3,3-hexafluoro-2-hydroxypropan-2-yl)phenyl )-1,2,3,4-tetrahydroisoquinoline-1-carboxamide (500 mg dissolved in about 120 mL methanol, injection volume 6.0mL) by Waters SFC 150 (room temperature, 100bar, 214nm) and 250* 25mm 10μm Dr.maish Reprosil Chiral-OM (similar to OD) (supercritical carbon dioxide: methanol, 70:30, 3.0min, 70mL / min) separation to obtain (R)-2-acetyl-6-(ethylsulfonyl)-N-(4-(1,1 ,1,3,3,3-hexafluoro-2-hydroxypropan-2-yl)phenyl)-1,2,3,4-tetrahydroisoquinoline-1-carboxamide or (S)-2- Acetyl-6-(ethylsulfonyl)-N-(4-(1,1,1,3,3,3-hexafluoro-2-hydroxypropan-2-yl)phenyl)-1,2, 3,4-Tetrahydroisoquino...
