YieldReaction ConditionsOperation in experiment
100% With triethylamine; In dichloromethane; at 20℃; for 2h; Example 2: Tetrahydropyridine 2 was prepared in 3 steps starting with the deprotection of 1 using Method 3. The resulting HCl amine salt was dissolved in dichloromethane (0.2 M). Benzyl chloroformate (1.2 equiv) was added followed by triethylamine (3.0 equiv). The reaction was allowed to stir at room temperature for 2h after which point it was diluted with IN HCl and extracted with excess dichloromethane. The organic layer was dried over MgSpsi4 and concentrated to provide the desired carbamate in quantitative yield, which was converted directly to boronic acid 2 using Method 2. [M-H]- = 260.1 m/z.

The cooled reaction mixture was diluted with H20 and extracted with EtOAc. The organic phasewas passed through a phase separator and concentrated onto flash silica (15 mL). The resulting powder was purified by column chromatography (normal phase, [Biotage SNAP cartridge KP-sil 50 g, 40-63 jim, 60 A], 40 mL per mm, 65percent Et20 in isohexane isochratic) to give benzyl 4-(1 ,3-thiazol-4-yl)-3,6-dihydropyridine-1 (2H)-oarboxylate (173 mg, 79percent).LCMS (Method C): mlz 301 (M+H) (ES?), at 1.46 mi UV active.

Then the reactionmixture was filtered, concentrated to remove solvent and diluted with ethyl acetate (180 mL) and water (50 mL). Separated organic part was dried over anhydrous Na2504, fitered and concentrated. Purification via ISCO system (ethyl acetate/petroleum ether) afforded the title product.LC-MS (ESI) [mobile phase: from 95% water (0.05% TFA) and 5% CH3CN to 5% water (0.05%TFA) and 95% CH3CN in 5.0 mm]: m/z 334 [M + H] Rt 3.50 mm.

The vial was sealed, evacuated and backfilled with N2. The reaction mixture was heated in the microwave at 120C for 45min and monitored by LCMS. The reaction mixture was concentrated in vacuo to give the crude material which was purified by Biotage column chromatography (see individual compounds for details of the eluent used).
