3-(azepan-1-yl)-N-methylpropan-1-amine

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

Procedure: To a solution of 1-((2-(4-chlorophenyl)-5-methyloxazol-4-yl)methyl)piperidine-4-carboxylic acid (A-3, 70 mg, 0.52 mmole), 3-(azepan-1-yl)-N-methylpropan-1-amine (20 mg) and DIPEA (0.05 mL) in DMF (2 mL) was added EDC (35 mg). The reaction solution was stirred at room temperature for 12 hours. The reaction was diluted with EtOAc (30 mL). The organic layer was washed with saturated sodium bicarbonate (10 mL), water (10 mL) and dried over anhydrous magnesium sulfate. After filtration and concentration, the residue was purified through chromatography (CH2Cl2:MeOH 10:1) to give N-(3-(azepan-1-yl)propyl)-1-((2-(4-chlorophenyl)-5-methyloxazol-4-yl)methyl)-N-methylpiperidine-4-carboxamide (42 mg, 82%). H1NMR (300 MHz, CDCl3), ppm: 7.97 (d, 2H), 7.48 (d, 2H), 3.80 (m, 1H), 3.63 (m, 2H), 3.45 (m, 2H), 3.31-3.14 (m, 7H), 2.75 (s, 3H), 2.44 (m, 4H), 2.01 (m, 2H), 1.85 (m, 10H), 1.30 (m, 2H), 1.26 (m, 2H). MS (ESI+) M/z: 487, 489 (M+H). The organic layer was washed with saturated sodium bicarbonate (10 mL), water (10 mL) dried over anhydrous magnesium sulfate After filtration and concentration the residue was purified through chromatography (CH2Cl2:MeOH 10:1)

Procedure: 3-(Azepan-1-yl)-N-benzyl-N-methylpropan-1-amine (100 mg) was dissolved in MeOH (20 mL) and to the solution was added 10% Pd/C (50 mg). The reaction mixture was shook under 50 psi hydrogen atmosphere for 2 h. The catalyst was filtered over Cellite and washed with methanol. The filtrated was evaporated to give 3-(azepan-1-yl)-N-methylpropan-1-amine, used without further purification. The catalyst was filtered over Cellite washed with methanol The filtrated was evaporated
