    摘要: This invention provides an industrially useful process for producing a quinazoline derivative (I) of the general formula: [wherein R1 is hydrogen or halogen; R2 is carboxy or protected carboxy; A is lower alkylene] or its salt on a commercial scale which comprises reacting a compound of the general formula: [wherein R1 is hydrogen or halogen] or its salt with a silylating agent and then with a compound of the general formula: Cl—A—R2  (III) [wherein R2 is carboxy or protected carboxy; A is lower alkylene] or its salt, optionally followed by desilylation.

    摘要: A glow plug (1) including a metallic shell (2) having a forward end portion (20) having an outer peripheral surface whose diameter increases toward the rear end side with respect to the axial direction, the forward end portion (20) coming into contact with a seat surface (55) formed on an internal combustion engine (50). The outer peripheral surface of the forward end portion (20) includes a first, second and third contact surfaces (21), (22) and (23), respectively, which differ in imaginary line angle from one another, the imaginary line angle of each contact surface being an angle which is formed, as viewed on a cross section including an axis C1, between two straight imaginary lines connecting inflection points of the contact surface at opposite ends of the contact surface. At least one of the contact surfaces is a curved surface which bulges outward.
