合成路线1
该中间体在本合成路线中的序号：(XVI)The optical resolution of amine (X), performed by treatment with (+)-mandelic acid in ethanol, followed by crystallization of the resulting salt and then treatment with Na2CO3 affords the desired (R)-enantiomer (XI). Compound (XI) is protected with Boc2O to give the corresponding carbamate (XII), which is deacetylated with NaOH in ethanol to yield the intermediate (XIII). Hydrolysis of the cyano group of (XIII) with NaOH and H2O2 in DMSO furnishes the corresponding carboxamide (XIV), which is condensed with 3-(tert-butyldimethylsilyloxy)propyl 4-nitrobenzenesulfonate (XV) by means of K2CO3 and a crown ether in dioxane to provide the indoline adduct (XVI). Finally, desilylation of (XVI) with TBAF in THF yields the 3-hydroxypropyl derivative (XVII), which by removal of the Boc-protecting group by means of TFA in dichloromethane gives KMD-3213.
