Abstract: Intermediates useful for preparing 4,6-diaminopyrimido[5,4-d]pyrimidines, which are themselves useful as inhibitors of signal transduction mediated by tyrosine kinases. The intermediates of the invention are 2-chloro-4,6-diamino-7,8-dihydropyrimido[5,4-d]pyrimidines, protected and unprotected 4-amino-2,6-dichloro-7,8-dihydropyrimido[5,4-d]pyrimidines and 4-amino-2,6,8-trichloropyrimido[5,4-d]pyrimidines.
Abstract: A system for testing systems which are in turn used to test the leaktightness of a hollow body is suggested. Instead of the hollow body, a test body (2) is placed in the system which generates a defined pressure increase in a measuring chamber (4) within a pre-determined time span. This defined pressure increase corresponds exactly to the pressure increase generated by a hollow body with a small amount of leakage, wherein the hollow body can still just be regarded as leaktight. The test body can be configured as a glass capillary which extends in a sealing manner between two chambers with different air pressure. Alternatively, the test body can comprise a material which can accept a defined amount of moisture from the ambient atmosphere during storage. A vacuum formed around the test body causes moisture to be withdrawn from the test body and at least partially evaporated in the vacuum, which again leads to an increase in pressure in the chamber.

Abstract: A method for crystallizing a substance, especially an inhalable medicament, comprising the following steps:
(a) dissolving said substance in a solvent, to produce a solution of said substance,
(b) producing a segmented stream which consists of alternating segments of said solution of the substance and of a transport medium,
(c) introducing said segmented stream into the first end of a retention stretch, which retention stretch has a first end and a second end, so that said segmented stream passes from said first end to said second end of said retention stretch, and exits from the second end of the retention stretch,
(d) cooling the retention stretch, to thereby bring about crystallization of the substance in the segments of solution, in the segmented stream, as said segmented stream passes through the retention stretch, and
(e) separating the crystals of material from the segmented stream as it exits from the second end of the retention stretch.
