    摘要: The present invention concerns processes for the production and purification of compounds of the formula: where R1-R10 are as defined in the specification. Preferred processes of the invention utilize a lithium bis(trimethylsilyl)amide, lithium dicyclohexylamide, or potassium bis(trimethylsilyl)amide base and a R1—X alkylating agent where X is as described in the specification. An alcohol preferably is added to the product solution is used to promote crystallization of the desired product.
