As per our interest to develop better protocols for the synthesis of biologically active heterocyclic molecules, we would like to report the synthesis of a series of new 3,4-dihydro-3-substituted-2H-naphtho[2,1-e][1,3] oxazine derivatives using 2 naphthol, formalin and various anilines as substrates in presence of Potassium Dihydrogen Phosphate catalyst.
Analytical grade potassium dihydrogen phosphate and orthophosphoric acid 99% were purchased from WINLAB (UK).
Phosphate salts, such as ammonium dihydrogen phosphate (N[H.sub.4][H.sub.2]P[O.sub.4]), potassium dihydrogen phosphate (K[H.sub.2]P[O.sub.4]), and sodium dihydrogen phosphate (Na[H.sub.2]P[O.sub.4]), were usually used to prepare MPC [10, 11].
Potassium dihydrogen phosphate (K[H.sub.2]P[O.sub.4], [greater than or equal to]0.995 mass fraction) and potassium nitrate (KN[O.sub.3], [greater than or equal to]0.995 mass fraction) are from Tianjin Bodi Chemical Holding Co., Ltd., China.
It was noticed that with Zorbax Eclipse XDB C8 (4.6 x 150 mm, 5 m) column and recommended mobile phase comprising acetonitrile - methanol - potassium dihydrogen phosphate (22+34+44 v/v), the desired results obtained were not according the chromatograms provided by European Pharmacopeia (EP), but by using another column (ACE 5 C8) (4.6 x 150 mm, 5 m), an extra peak of diazepam degradant was obtained, which showed that by using appropriate mobile phase containing CH3CN- CH3OH- KH2PO4 (20+32+48 v/v), the better results can be achieved.
In recent years, with applying high power laser systems in important technologies, including controlled thermonuclear reactions and simulating nuclear explosions, as preferred material of frequency converters and electrooptic switches in Inertial Confinement Fusion (ICF) [1], potassium dihydrogen phosphate (KDP) crystal has attracted scientists' widespread attention.
The best mobile phase combination was acetonitrile and 15 mM potassium dihydrogen phosphate solution.
Potassium dihydrogen phosphate (KDP), with good physical properties including large nonlinear optical coefficient, good structural quality, and mechanical properties, is used in many large-aperture laser systems as frequency conversion crystal and electrooptic switching.

Calibration of the method was achieved using standard solutions of potassium dihydrogen phosphate, K[H.sub.2]P[O.sub.4] (purchased from Sigma Aldrich) in reaction with ammonium molybdate and stannous chloride.
