실험 절차

A suspension of (E)-3-{4-oxo-spiro[chromane-2,4′-piperidine]-6-yl}-acrylic acid methyl ester (169 mg, 0.500 mmol, Intermediate 1, hydrochloride salt) in 1 M Na2CO3, was stirred for 10 minutes, then extracted with DCM and treated with N-methyl-indol-2-carbaldehyde (95 mg, 0.60 mmol) and sodium triacetoxyborohydride (159 mg, 0.750 mmol) following the procedure described in Example 55, Step A, giving (E)-3-{1′-(1-methyl-1H-indol-2-ylmethyl)-4-oxo-spiro[chromane-2,4′-piperidine]-6-yl}-acrylic acid methyl ester (179 mg) as a white solid. The resulting ester was hydrolyzed as described in Example 55, Step B, giving (E)-3-{1′-(1-methyl-1H-indol-2-ylmethyl)-4-oxo-spiro[chromane-2,4′-piperidine]-6-yl}-acrylic acid (187 mg) as an orange solid (hydrochloride salt). The product was suspended in DCM (3 ml), TEA (0.08 ml, 0.58 mmol) was added, and the clear solution was treated with NH2OTHP following the procedure described in Example 1, Step B, giving (E)-3-{1′-(1-methyl-1H-indol-2-ylmethyl)-4-oxo-spiro[chromane-2,4′-piperidine]-6-yl}-N-(tetrahydro-pyran-2-yloxy)-acrylamide (37 mg) as a light yellow solid. The compound was then dissolved in DCM (3 ml) and treated with 4 M HCl in dioxane (0.1 ml, 0.4 mmol) as described in Example 55, Step D, giving a light yellow solid after aqueous workup and column chromatography (eluent: DCM/MeOH 99:1 to 95:5) (7 mg, free base)
