    摘要: Processes for preparing certain N-arylalkyl-1-(alkyl or aralkyl)-2-acylaminoalkyl-5-hydroxy-6-oxo-1,6-dihydropyrimidine-4-carboxamides are disclosed. In one embodiment, the process comprises acylating the free amine in the corresponding N-arylalkyl-1-(alkyl or aralkyl)-2-aminoalkyl-5-ester protected hydroxy-6-oxo-1,6-dihydropyrimidine-4-carboxamide and then deprotecting the 5-hydroxy by base hydrolysis. The hydroxypyrimidinone carboxamide products of the process are HTV integrase inhibitors which are useful for treating HTV infection, treating AIDS, or delaying the onset or progression of AIDS. Certain esterified N-arylalkyl hydroxypyrimidinone carboxamides that can be employed as process intermediates are also disclosed.

    摘要: By this invention, there is provided a process for producing crystalline 4,7.beta.-dimethyl-4-aza-5.alpha.-cholestan-3-one of structural formula (I) from 4,7.beta.-dimethyl-4-aza-5.alpha.-cholestan-3-one oil. ##STR1## This crystallization process of the present invention comprises crystallization of the oil optionally containing residual solvent with vigorous but controlled agitation. Preferably, this crystallization process is carried out at select and controlled temperatures. Further, 4,7.beta.-dimethyl-4-aza-5.alpha.-cholestan-3-one has been found to exist in at least two novel polymorphic nonsolvated forms, herein referred to as Form I and Form II. Form I can be prepared pure by careful control of the crystallization process.
