Interference No. 102,408 no. 1 at Lederle by (CR355):14 [T]reating 945 mg. of 3,3-oxetainedimethanamine in 40 cc of water with 820 mg. of sodium acetate and 2.075 g of potassium tetrachloroplatinate. The mixture was stirred for three hours and filtered. The filtered crystals weighed 0.37g; mp 262 dec. and were labeled “A”. The filtrate was allowed to stand overnight and then the resulting solid was collected giving 440 mg of product as bright yellow crystals melting at 270-272E which was labeled “B”. Compare CR365 (product labeled "A" described as beige solid having melting point of 262E; product "B" described as bright yellow crystals having melting point of 270-273E). Products labeled “C”, “D” and “E” also appear to have been prepared during the process (CR365). Various notations have been used throughout the record to identify products which appear to be described on page 47 of notebook 12459B. For example, a request for infrared analysis prepared by Ralph G. Child uses the notation "sample no. 12459B-47B" to identify one such compound. See CR356, ¶ 4; 15 14American Cyanamid Company, Lederle Laboratories Division, Pearl River, New York, USA (hereinafter "Lederle"). 15Presumably, the notation "12459B-47B" is intended to identify the product labeled "B" on page 47 of Child's notebook 12459B, the preparation of which is described therein. Compare CR365 (product "B" described as "bright yellow crystals wt=0.44 mp 270-273E") with CR366 ("[Stru]cture, Color and State [:] yellow crystals [;] BP or 12Page: Previous 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 NextLast modified: November 3, 2007
